[0038] The user terminal 16 includes a display control unit 30, an acquisition unit 32, a transmission unit , a reception unit , an input reception unit , a determination unit 40, and a camera control unit .

[0039] The display control unit 30 causes a display unit such as the display 418 to display a screen. For example, the display control unit 30 causes the display unit to display a first screen including an image being captured by the capture function, which is a first screen that displays a capture assist screen for a book code image. The book code image is, for example, a barcode image or a two-dimensional code image that can identify code information such as a book JAN code or ISBN code. For example, the display control unit 30 causes the display unit to display a first screen including the barcode image of the book being captured by the camera.

[0040] The acquisition unit 32 acquires book identification information from the code image captured by the camera in response to the inclusion of a book code image in the image being captured. For example, the acquisition unit 32 acquires an ISBN code from the barcode image captured by the camera in response to the inclusion of a book barcode image in the image being captured.

[0041] The transmitting unit 34 transmits information such as the book identification information to the server device 10. For example, the transmitting unit 34 transmits to the server device 10 an ISBN code obtained from the barcode image.

[0042] The receiving unit 36 ​​receives from the server device 10 search results searched by information such as the book identification information transmitted to the server device 10, and book information including at least the book titles of the books. For example, the receiving unit 36 ​​receives from the server device 10 search results searched by the ISBN codes transmitted to the server device 10, and book information including at least the book titles of the books.

[0043] Furthermore, the display control unit 30 causes the display unit to display a second screen that displays at least the received search results and the book title included in the book information, and that includes a display button (an example of a display component) that can accept an instruction to purchase the book if the book is not in the facility's collection. If the book is in the facility's collection, the display control unit 30 displays the facility's collection management information for the book on the second screen. For example, if the book is in the library's collection, the display control unit 30 displays the library management information, such as the library's storage location and lending status, included in the received book information on the second screen.

[0044] Furthermore, when the transmission unit 34 receives a purchase request instruction from the user via the second screen, the transmission unit 34 transmits to the server device 10 information on a purchase request for the book whose title is displayed on the second screen.

[0045] Furthermore, the display control unit 30 causes the display unit to display a third screen including a book title input field. For example, the book title input field is an input field in which the user inputs a word or phrase contained in the book title of the book they want to search for in order to use the book search function.

[0046] The transmitting unit 34 transmits the phrase entered in the book title entry field to the server device 10.

[0047] The receiving unit 36 ​​receives, from the server device 10, book information of books that are searched for using the term transmitted to the server device 10 and that include the term transmitted to the server device 10 in their book titles. For example, the receiving unit 36 ​​receives, from the server device 10, book information that includes at least the book titles of books that are searched for using the term transmitted to the server device 10.

[0048] The display control unit 30 causes the display unit to display a fourth screen that displays the titles of one or more books included in the book information received from the server device 10 and accepts the user's selection of one book from the one or more books. If the book selected by the user from the fourth screen is not in the facility's library, the display control unit 30 causes the display unit to display a second screen that accepts the user's instruction to purchase the book. If the book selected by the user from the fourth screen is in the facility's library, the display control unit 30 displays the facility's library management information for the book included in the received book information on the second screen.

[0049] The display control unit 30 displays a fifth screen on the display unit to prompt the user to select either a first search for searching for books by book identification information or a second search for searching for books by phrase. For example, the display control unit 30 displays a fifth screen on the display unit to prompt the user to select either a search for books by ISBN code or a search for books by phrase.

[0050] The receiving unit 36 ​​receives from the server device 10 a response to the information on the book purchase request transmitted to the server device 10.

[0051] If the response indicates that the information on the book purchase request has already been accepted, the display control unit 30 displays on the display unit that the book purchase request has been accepted. Also, if the display control unit 30 receives a response from the server device 10 indicating that the information on the book purchase request has been accepted, the display control unit displays on the display unit that the book purchase request has been accepted.

[0052] The input receiving unit 38 receives operation input from a user operating the user terminal 16. The input receiving unit 38 may receive operation input from a user operating the user terminal 16 by manual input or voice input. The determination unit 40 performs determination processing. For example, the determination unit 40 performs determination processing on the content of the operation input, determination processing on the content of the captured image, or determination processing on the processed results. The camera control unit 42 controls the image capturing function, such as starting up the camera.

[0053] The server device 10 shown in FIG. 4 includes an access control unit 60, a request receiving unit 62, a search unit 64, a response unit 66, and a purchase request management unit 68.

[0054] The access control unit 60 controls access by users of the user terminals 16. The access control unit 60 controls access from the user terminals 16 to the server device 10, thereby restricting at least one of the users and the period for which book purchase requests are accepted from the user terminals 16.

[0055] For example, the access control unit 60 may perform access control so as not to permit access from users other than those set as users who accept purchase requests. Also, the access control unit 60 may perform access control so as not to permit access outside the period during which purchase requests are accepted.

[0056] The request receiving unit 62 receives various requests from the user terminal 16. For example, the request receiving unit 62 receives from the user terminal 16 a login request, a library search request, a book search request, a purchase request, and the like.

[0057] The search unit 64 uses the book information management server device 14 to search for book information that includes at least the book title of the book based on the book identification information received from the user terminal 16. For example, the search unit 64 searches for book information that includes at least the book title of the book based on the ISBN code received from the user terminal 16. The search unit 64 may also search for book information that includes the phrase received from the user terminal 16 in the book title.

[0058] The search unit 64 uses the book collection management server device 12 to search for whether or not a book with the searched book name is in the facility's book collection. The search unit 64 may also search for whether or not a book with book identification information received from the user terminal 16 is in the facility's book collection. For example, the search unit 64 searches for whether or not a book specified by a book name or ISBN code is in the library's book collection. The response unit 66 responds to the user terminal 16 with the search results searched by the search unit 64.

[0059] The search result returned by the response unit 66 includes information as to whether or not the book with the title searched for by the search unit 64 is in the library's collection.

[0060] The purchase request management unit 68 manages information (hereinafter referred to as purchase request information) indicating a desire to purchase a book received from one or more users. When the purchase request management unit 68 receives purchase request information from the user terminal 16, if the purchase request information is not for a book for which purchase request information has already been received but is information on a new purchase request, the purchase request management unit 68 adds the information to previously received purchase request information, which will be described later, and manages it. Previously received purchase request information is information on books for which purchase requests have been received in the past, and is managed in the form of a list, for example (hereinafter referred to as a purchase request list). Note that, among the past purchase request information, items that have already been purchased and are in the library may be deleted from the list.

[0061] The book management server device 12 manages an online book catalog, which is an example of information about the library's books. The online book catalog is used, for example, to provide a book search function to users of the user terminals 16. The book search function may use book JAN codes or ISBN codes, or may include searches by book titles (book names) or keywords, etc.

[0062] The book information management server device 14 provides a book search function that uses book information including book titles (book names) or keywords (phrases), etc. to search for book information using book names or phrases as search keys. The book information management server device 14 may be realized by an information processing device or a cloud service.

[0065] In step S10, the input accepting unit 56 of the user terminal 16 accepts from the user an operation to launch, for example, the library app 1000 of Fig. 6. The display control unit 30 displays a login screen 1002. Note that the display control unit 30 may display the login screen 1002 if there is no cache of the previous login state, and may display the menu screen 1004 if there is a cache. The display control unit 30 may use a session cookie to switch between displaying the login screen 1002 and the menu screen 1004.

[0066] In step S12, the display control unit 30 accepts input of a username and password from the user on the login screen 1002. In step S14, when the login button 1003 is operated, the display control unit 30 proceeds to step S16, requests authentication processing from the access control unit 60 of the server device 10, and acquires the result of the authentication processing.

[0067] In step S18, if the result of the authentication process is not successful, in other words, if the authentication is unsuccessful, the display control unit 30 displays an authentication failure screen 1008. Furthermore, if the result of the authentication process is successful, the display control unit 30 displays a menu screen 1004.

[0068] When the book search button 1005 on the menu screen 1004 is operated, the display control unit 30 displays the book search top screen. When the purchase request button 1006 on the menu screen 1004 is operated, the display control unit 30 displays the purchase request top screen.

[0069] 《Select the top screen of the book search》 7 is a flowchart showing an example of a processing procedure after displaying the library search top screen of the information processing system 1 according to this embodiment. FIG. 8 is a diagram showing an example of a screen image displayed on the user terminal 16.

[0070] When the user operates the book search button 1005 on the menu screen 1004, the display control unit 30 displays a book search top screen 1100. The book search top screen 1100 is an example of the fifth screen.

[0071] In step S30, if the "Search by book title" button 1102 on the library search top screen 1100 is operated (e.g., pressed), the display control unit 30 proceeds to the process of step S50. If the "Search by book title" button 1102 is not operated, the display control unit 30 proceeds to the process of step S32.

[0072] In step S32, the determination unit 40 of the user terminal 16 determines whether or not the "Search by ISBN" button 1104 on the book search top screen 1100 has been operated.

[0073] If it is determined that the "Search by ISBN" button 1104 has been operated, then in step S34 the display control unit 30 displays the ISBN input screen 1200. In step S36, the determination unit 40 determines whether the camera capture button 1204 on the ISBN input screen 1200 has been operated.

[0074] If it is determined that the camera capture button 1204 on the ISBN input screen 1200 has been operated, the camera control unit 42 proceeds to step S38 and activates the camera. In addition, the display control unit 30 displays a capture screen 1300. The capture screen 1300 is an example of a first screen.

[0075] The photographing screen 1300 is a screen for photographing the barcode of the ISBN code of a book, and the image being photographed by the camera is displayed in an area 1302. The area 1302 may display a guide (frame) for displaying the barcode.

[0076] In step S40, the user adjusts the positions of the user terminal 16 and the book so that the barcode of the book's ISBN code is within the camera's shooting range. The display control unit 30 repeats the process of step S40 until the determination unit 40 determines that the barcode of the book's ISBN code has been photographed. When the determination unit 40 determines that the barcode of the book's ISBN code has been photographed, the display control unit 30 proceeds to step S42. When the barcode of the book's ISBN code is displayed in area 1302 of the shooting screen 1300, the determination unit 40 determines that the barcode has been photographed.

[0077] In step S42, the acquisition unit 32 acquires the ISBN code from the barcode in response to the barcode of the ISBN code of the book being included in the area 1302 of the photographed screen 1300. Note that the acquisition unit 32 may identify the ISBN code from the image using an OCR (Optical Character Recognition / Reader) function or the like.

[0078] In step S44, the display control unit 30 displays the ISBN code acquired in step S42 in the ISBN input field 1202 of the ISBN input screen 1200, and then proceeds to step S46. Note that the user may manually input the ISBN code into the ISBN input field 1202. Manual input includes touch screen input, keyboard input, and handwritten input using a stylus pen (a pen-type input device). If the user manually inputs the ISBN code into the ISBN input field 1202, the process proceeds from step S36 to step S46.

[0079] In step S46, when the library search button 1206 is operated while an ISBN code is displayed in the ISBN input field 1202 on the ISBN input screen 1200, the transmission unit 34 transmits a search request for the online library catalog including the ISBN code displayed in the ISBN input field 1202 to the server device 10.

[0080] The server device 10, which has received a search request for an online library catalog including an ISBN code, performs the processing shown in Fig. 9. Fig. 9 is a flowchart showing an example of the processing procedure of the server device 10 for performing search processing.

[0081] In step S100, the search unit 64 of the server device 10 searches the online library catalog for a book corresponding to the ISBN code received from the user terminal 16. If the book corresponding to the ISBN code received from the user terminal 16 is in the library's collection, the search unit 64 searches for book information and collection management information for that book. On the other hand, if the book corresponding to the ISBN code received from the user terminal 16 is not in the library's collection, the search unit 64 searches for book information for the book corresponding to the ISBN code received from the user terminal 16. The book information includes at least the title of the book corresponding to the ISBN code.

[0082] In step S102, if the library has a book corresponding to the received ISBN code, the response unit 66 generates a search result that includes book information and book management information for the book corresponding to the ISBN code, and information indicating that the book is included in the library's collection.

[0083] In addition, if the library does not have a book corresponding to the received ISBN code, the response unit 66 generates a search result including book information for the book corresponding to the ISBN code and information indicating that the book is not included in the library's collection.

[0084] In step S104, the response unit 66 transmits the search results generated in step S102 to the user terminal 16. Returning to step S48 in Fig. 7, the receiving unit 36 ​​of the user terminal 16 receives the search results in response to the online library catalog search request transmitted in step S46.

[0085] In step S30, when the "Search by book title" button 1102 on the library search top screen 1100 is operated, the display control unit 30 proceeds to the processing of step S50.

[0086] In step S50, the display control unit 30 displays a book title input screen 1400. The book title input screen 1400 is an example of a third screen.

[0087] In step S52, the input receiving unit 56 receives from the user an input of a phrase (at least a part of the book title) into the book title input field 1402 of the book title input screen 1400. When the book title search button 1404 is operated, the transmission unit 34 transmits to the server device 10 a search request for books that include the phrase input into the book title input field 1402.

[0088] The server device 10, which has received a search request for books containing the term entered in the book title entry field 1402, performs, for example, the processing shown in Fig. 10. Fig. 10 is a flowchart illustrating an example of the processing procedure of the server device 10 for performing the search processing.

[0089] In step S110, the search unit 64 of the server device 10 uses the book search function of the book information management server device 14 to search for one or more books whose titles match or partially match the words received from the user terminal 16. The search unit 64 also uses the book search function of the book information management server device 14 to search for ISBN codes corresponding to books whose titles match or partially match the words received from the user terminal 16.

[0090] In step S112, the search unit 64 stores the search results in which the ISBN code is associated with each book searched for in step S110. In step S114, the response unit 66 transmits the book information of the books searched for using the received phrase to the user terminal 16 as the search results.

[0091] 7, the receiving unit 36 ​​receives the search results for the search request transmitted in step S52. In step S56, the display control unit 30 displays a search result list screen 1500. The search result list screen 1500 is an example of a fourth screen.

[0092] Search result list screen 1500 is a screen that displays book titles 1502 of one or more books included in the search results received in step S54, and is a screen that accepts the selection of one book from the one or more book titles 1502. Search result list screen 1500 shows an example of accepting the selection of one book from the user using a radio button, and shows a state in which the selection of a book titled "Easy-to-Understand How to Use AI" has been accepted from the user.

[0093] In step S58, when the book search button 1504 is operated after the selection of one book has been accepted from the search result list screen 1500, the transmission unit 34 transmits the book information of the book selected from the search result list screen 1500 to the server device 10 and makes a search request for the online book catalog.

[0094] Proceeding to step S116 in FIG. 10, the request receiving unit 62 of the server device 10 receives the book information of the book selected from the search result list screen 1500 and receives a request to search the library's books.

[0095] In step S118, the search unit 64 of the server device 10 uses the ISBN code of the book for which the book information was received to make a book search request to the book management server device 12 to determine whether the book selected from the search result list screen 1500 is included in the online book catalog.

[0096] If a book selected from the search result list screen 1500 is in the library's collection, the search unit 64 obtains search results indicating that the book selected by the user is in the library's collection and book collection management information for the book from the book collection management server device 12. If a book selected from the search result list screen 1500 is not in the library's collection, the search unit 64 obtains search results indicating that the book selected by the user is not in the library's collection from the book collection management server device 12.

[0097] In step S120, if the book selected by the user is in the library's collection, the response unit 66 generates a search result including book information and collection management information of the book selected by the user and information indicating that the book is included in the library's collection. Also, if the book selected by the user is not in the library's collection, the response unit 66 generates a search result including information indicating that the book selected by the user is not included in the library's collection.

[0098] In step S122, the response unit 66 transmits the search results generated in step S120 to the user terminal 16. Returning to step S60 in Fig. 7, the receiving unit 36 ​​of the user terminal 16 receives the search results in response to the online library catalog search request transmitted in step S58.

[0099] Proceeding to step S62, the determination unit 40 refers to the search results received from the server device 10 in step S48 or step S60 and determines whether or not the book is in the library's collection.

[0100] If the book is in the library's collection, the display control unit 30 proceeds to step S64 and displays a book-in-stock search results screen 1700. The book-in-stock search results screen 1700 displays the title of the book selected from the search result list screen 1500, information indicating that the book is included in the library's collection, and the book's collection management information in the library. For example, the book-in-stock search results screen 1700 shown in Fig. 8 displays the location where the book is stored (shelf 2F-D) and the loan status (available for loan) as an example of the book's collection management information in the library.

[0101] If the book is not in the library's collection, the display control unit 30 proceeds to step S66 and displays a search results screen 1600 for books not in stock. The search results screen 1600 for books not in stock is an example of a second screen. The search results screen 1600 for books not in stock displays the title of a book selected from the search results list screen 1500, information indicating that the book is not in the library's collection, and a purchase request button 1602. The purchase request button 1602 on the search results screen 1600 for books not in stock is an example of a display component that accepts an operation from the user to request the purchase of a book whose title is displayed on the search results screen 1600 for books not in stock. Although a button is used below, it may also be in the form of a graphic icon or a link.

[0102] In step S68, the determination unit 40 determines whether or not the user has operated the purchase request button 1602 on the search results screen 1600 for no books in stock. If the user has operated the purchase request button 1602 on the search results screen 1600 for no books in stock, the process proceeds to step S70, where the transmission unit 34 transmits to the server device 10 information requesting the purchase of the book with the book title displayed on the search results screen 1600 for no books in stock. If the user has not operated the purchase request button 1602 on the search results screen 1600 for no books in stock, the transmission unit 34 skips the process of step S70.

[0103] "Purchase request" Fig. 11 is a flowchart showing an example of the processing procedure of the server device 10 after a user submits a purchase request from the search result screen 1600 for books that are not in stock. Fig. 12 is a flowchart showing an example of the processing procedure of the user terminal 16 after a user submits a purchase request from the search result screen 1600 for books that are not in stock. Fig. 13 is a diagram showing the configuration of an example of a purchase request list. Fig. 14 is a diagram showing an example of a screen image displayed on the user terminal 16.

[0104] When the purchase request management unit 68 of the server device 10 receives information on a book purchase request from the user terminal 16, in step S130 shown in Figure 11, it searches to see if the book for which the information on the book desired to be purchased from the user terminal 16 has been received is included in the purchase request list shown in Figure 13 (information on purchase requests received in the past).

[0105] The purchase wish list shown in Figure 13 has the following items: record ID, user ID, purchase request received date, and ISBN code. Note that these items are just examples, and other items may be included. The record ID is an example of identification information that identifies a record in the purchase wish list. The user ID is an example of identification information that identifies a user who has submitted a purchase request for a book. The purchase request received date is an example of date information on which a purchase request for a book is received from a user. The ISBN code is an example of identification information for a book for which a purchase request has been accepted from a user. The books registered in the purchase wish list in Figure 13 are books for which purchase requests have already been accepted from one or more users (books for which purchase requests have been accepted in the past).

[0106] In step S132, the purchase request management unit 68 refers to the purchase request list and determines whether a purchase request has been received in the past for the book for which purchase request information has been received from the user terminal 16. If a purchase request has been received in the past, the response unit 66 generates a result in response to the purchase request including information indicating that the purchase request has already been received in step S134. Proceeding to step S140, the response unit 66 transmits the result in response to the purchase request generated in step S134 to the user terminal 16.

[0107] In step S132, if the book for which purchase request information has been received from the user terminal 16 has not been previously accepted for purchase, the purchase request management unit 68 performs the process of step S136. In step S136, the purchase request management unit 68 registers the book for which purchase request information has been received in step S130 in the purchase request list.

[0108] In this way, if the purchase request management unit 68 receives purchase request information from the user terminal 16 for a book for which a purchase request has been accepted in the past, it does not register the book in the purchase request list to avoid duplicate purchase requests being registered. Also, if the purchase request management unit 68 receives purchase request information from the user terminal 16 for a book for which a purchase request has not been accepted in the past, it registers the book in the purchase request list as a new book purchase request.

[0109] In step S138, the response unit 66 generates a result for the purchase request, including information indicating that the purchase request has been accepted. In step S140, the response unit 66 transmits the result for the purchase request generated in step S138 to the user terminal 16.

[0110] In step S150 shown in FIG. 12, the receiving unit 36 ​​of the user terminal 16 receives the result of the purchase request sent to the server device 10 in step S70 of FIG.

[0111] In step S152, the determination unit 40 of the user terminal 16 refers to the result of the received purchase request and determines whether a purchase request for the book requested in step S70 has been received in the past.

[0112] If it is determined in step S70 that a purchase request for the book requested has been received in the past, the display control unit 30 proceeds to step S154 and displays the purchase request result screen 2000 of Fig. 14. The purchase request result screen 2000 of Fig. 14 displays that the purchase request has been received.

[0113] Furthermore, if it is determined in step S70 that a purchase request for the book requested has not been accepted in the past, the display control unit 30 proceeds to step S156 and displays the purchase request result screen 2100 of Fig. 14. The purchase request result screen 2100 displays that a purchase request has already been accepted.

[0114] In this way, according to the information processing system 1 of this embodiment, when a user wishes to request a book from a library, the user can easily check whether the book is in the library's collection.

[0115] Furthermore, according to the information processing system 1 of this embodiment, if a user has a book that he or she would like to request from a library to purchase, and the library has not yet requested the user to purchase that book, the user can easily request the library to purchase that book.

[0116] 《Select the top page of your desired purchase》 15 is a diagram showing an example of a screen image displayed on the user terminal 16. When the purchase request button 1006 on the menu screen 1004 is operated, the display control unit 30 displays a purchase request top screen.

[0117] When the user operates the purchase request button 1006 on the menu screen 1004, the display control unit 30 displays a purchase request top screen 3000. The purchase request top screen 3000 is an example of a fifth screen.

[0118] The determination unit 40 determines whether or not the "Search by ISBN" button 3004 on the purchase request top screen 3000 has been operated. If it is determined that the "Search by ISBN" button 3004 has been operated, the display control unit 30 displays the ISBN input screen 3100. The determination unit 40 determines whether or not the camera capture button 3104 on the ISBN input screen 3100 has been operated.

[0119] When it is determined that the camera capture button 3104 on the ISBN input screen 3100 has been operated, the camera control unit 42 activates the camera. In addition, the display control unit 30 displays a capture screen 3200. The capture screen 3200 is an example of a first screen.

[0120] The photographing screen 3200 is a screen for photographing the barcode of the ISBN code of a book, and the image being photographed by the camera is displayed in an area 3202. A guide (frame) for displaying the barcode may be displayed in the area 3202. The user adjusts the positions of the user terminal 16 and the book so that the barcode of the ISBN code of the book falls within the photographing range of the camera. The determination unit 40 determines that the barcode has been photographed when the barcode of the ISBN code of the book is displayed in the area 3202 of the photographing screen 3200.

[0121] The acquisition unit 32 acquires the ISBN code from the barcode in response to the barcode of the ISBN code of the book being included in the area 3202 of the photographing screen 3200. The display control unit 30 displays the acquired ISBN code in the ISBN input field 3102 of the ISBN input screen 3100.

[0122] When the decision button 3106 is operated while an ISBN code is displayed in the ISBN input field 3102 on the ISBN input screen 3100, the transmission unit 34 transmits a purchase request including the ISBN code displayed in the ISBN input field 3102 to the server device 10.

[0123] When the server device 10 receives a purchase request including an ISBN code, the search unit 64 searches the online library catalog for a book corresponding to the received ISBN code. If the library has a book corresponding to the received ISBN code, the search unit 64 searches the book information and library management information for that book. If the library does not have a book corresponding to the received ISBN code, the search unit 64 searches for book information for the book corresponding to the received ISBN code. The book information includes at least the title of the book corresponding to the ISBN code.

[0124] If the library has a book corresponding to the received ISBN code, the response unit 66 generates a search result that includes book information and book management information for the book corresponding to the ISBN code, and information indicating that the book is included in the library's collection.

[0125] In addition, if the library does not have a book corresponding to the received ISBN code, the response unit 66 generates a search result including book information for the book corresponding to the ISBN code and information indicating that the book is not included in the library's collection.

[0126] The response unit 66 transmits the generated search results to the user terminal 16. The receiving unit 36 ​​of the user terminal 16 receives the search results in response to the transmitted purchase request.

[0127] When the "Search by book title" button 3002 on the purchase request top screen 3000 is operated, the display control unit 30 displays a book title input screen 3300. The book title input screen 3300 is an example of a third screen.

[0128] The input receiving unit 56 receives, from the user, an input of a phrase (at least a part of a book title) into the book title input field 3302 of the book title input screen 3300. When the book title search button 3304 is operated, the transmission unit 34 transmits to the server device 10 a search request for books that include the phrase input into the book title input field 3302.

[0129] The search unit 64 of the server device 10, which has received a search request for books containing the phrase entered in the book title input field 3302, searches for one or more books whose titles match or partially match the received phrase, using the book search function of the book information management server device 14. The search unit 64 searches for the ISBN codes of books whose titles match or partially match the received phrase, using the book search function of the book information management server device 14. The search unit 64 also saves the search results, each of which is associated with an ISBN code.

[0130] The response unit 66 transmits the book information of the books searched for using the received phrase to the user terminal 16 as the search results. The receiving unit 36 ​​of the user terminal 16 receives the search results for the transmitted search request. The display control unit 30 displays a search result list screen 3400. The search result list screen 3400 is an example of a fourth screen.

[0131] The search result list screen 3400 is a screen that displays book titles 3402 of one or more books included in the received search results, and is a screen that accepts the selection of one book from the one or more book titles 3402. The search result list screen 3400 shows an example of accepting the selection of one book from the user using a radio button, and shows a state in which the selection of a book titled "Easy-to-Understand How to Use AI" has been accepted from the user.

[0132] When the decision button 3404 is operated after the selection of one book has been accepted from the search result list screen 3400, the transmission unit 34 transmits the book information of the book selected from the search result list screen 3400 to the server device 10 and makes a purchase request.

[0133] The request receiving unit 62 of the server device 10 receives the book information of the book selected from the search result list screen 3400 and receives a purchase request.

[0134] The search unit 64 of the server device 10 uses the ISBN code of the book for which the book information has been received to make a book search request to the book management server device 12 to determine whether the book selected from the search result list screen 3400 is included in the online book catalog.

[0135] If a book selected from the search result list screen 3400 is in the library's collection, the search unit 64 obtains search results indicating that the book selected by the user is in the library's collection and book collection management information for the book from the book collection management server device 12. If a book selected from the search result list screen 3400 is not in the library's collection, the search unit 64 obtains search results indicating that the book selected by the user is not in the library's collection from the book collection management server device 12.

[0136] If the book selected by the user is in the library's collection, the response unit 66 generates a search result including book information and collection management information of the book selected by the user and information indicating that the book is included in the library's collection. Also, if the book selected by the user is not in the library's collection, the response unit 66 generates a search result including information indicating that the book selected by the user is not included in the library's collection.

[0137] The response unit 66 transmits the generated search results to the user terminal 16. The receiving unit 36 ​​of the user terminal 16 receives the search results in response to the transmitted purchase request.

[0138] The display control unit 30 refers to the search results for the purchase request received from the server device 10 and determines whether the book is available in the library's collection.

[0139] If the book is in the library's collection, the display control unit 30 displays a book-in-stock search results screen 3600. The book-in-stock search results screen 3600 displays the title of a book selected from the search result list screen 3400, information indicating that the book is included in the library's collection, and the book's collection management information in the library. For example, the book-in-stock search results screen 3600 shown in Fig. 15 displays the location of the book (shelf 2F-D) and the loan status (available for loan) as an example of the book's collection management information in the library.

[0140] Furthermore, if the book is not in the library's collection, the display control unit 30 displays a search results screen 3500 for no books in stock. The search results screen 3500 for no books in stock is an example of a second screen. The search results screen 3500 for no books in stock displays the name of a book selected from the search results list screen 3400, information indicating that the book is not included in the library's collection, and a purchase request button 3502. The purchase request button 3502 on the search results screen 3500 for no books in stock is a button that accepts an operation from the user to request the purchase of a book whose name is displayed on the search results screen 3500 for no books in stock.

[0141] The determination unit 40 determines whether or not a user has operated the purchase request button 3502 on the search result screen 3500 for no books in stock. If a user has operated the purchase request button 3502 on the search result screen 3500 for no books in stock, the transmission unit 34 transmits to the server device 10 information on a desire to purchase the book of the book title displayed on the search result screen 3500 for no books in stock.

[0142] The processing performed after sending the information regarding the desire to purchase the book with the title displayed on the search results screen 3500 for books not in stock to the server device 10 is the same as the processing described using Figures 11 to 14, and therefore will not be described again.

[0143] In this way, according to the information processing system 1 of this embodiment, when a user wishes to request a book from a library, the user can easily check whether the book is in the library's collection.

[0144] Furthermore, according to the information processing system 1 of this embodiment, if a user has a book that he or she wishes to request from a library to purchase, but has not yet requested from the library to purchase that book, the user can easily request from the library to purchase that book. In particular, if the user participates in a book fair or the like as shown in Fig. 19, the user can request from the library to purchase the book without leaving the venue.

[0145] [Second embodiment] The first embodiment shows an example in which a user requests the purchase of books one by one. The second embodiment shows an example in which a user requests the purchase of multiple books at once. Note that the second embodiment shown below is similar to the first embodiment except for some parts, and therefore the description will be omitted as appropriate.

[0146] <Processing> 《App launch》 As described above in the first embodiment, the information processing system 1 according to this embodiment displays a menu screen of the information processing system 1. Fig. 16 is a flowchart illustrating an example of a processing procedure after displaying the menu screen 4000 of the information processing system 1 according to this embodiment. Fig. 17 is a diagram illustrating an example of a screen image displayed on the user terminal 16.

[0147] When the start button 4002 on the menu screen 4000 is operated, the camera control unit 42 of the user terminal 16 starts up the camera. In addition, the display control unit 30 displays a shooting screen 4100. The shooting screen 4100 is an example of a first screen.

[0149] In step S202, the user adjusts the positions of the user terminal 16 and the book so that the barcode of the book's ISBN code is within the camera's shooting range. The determination unit 40 repeats the process of step S202 until it determines that the barcode of the book's ISBN code has been photographed. If it is determined that the barcode of the book's ISBN code has been photographed, the acquisition unit 32 proceeds to step S204. If the barcode of the book's ISBN code is displayed in area 4102 on the shooting screen 4100, the determination unit 40 determines that the barcode has been photographed.

[0150] In step S204, the acquisition unit 32 acquires the ISBN code from the barcode in response to the barcode of the ISBN code of the book being included in the area 4102 of the photographed screen 4100. The acquisition unit 32 may identify the ISBN code from the image using an OCR function or the like. In step S206, the acquisition unit 32 stores the ISBN code acquired in step S204 in a memory such as the RAM 403.

[0151] In step S208, the display control unit 30 displays the ISBN code identified in step S204 on the book selection screen 4200. When the next book button 4202 on the book selection screen 4200 is operated, the display control unit 30 returns to step S200 and continues book selection.

[0152] Furthermore, when the complete button 4204 on the book selection screen 4200 is operated, the display control unit 30 proceeds to step S212 and reads out the ISBN codes stored in memory. The display control unit 30 displays a list of the ISBN codes read out in step S212 on the book selection screen 4300. The book selection screen 4300 is an example of the sixth screen.

[0153] When the Add Book button 4302 on the book selection screen 4300 is operated, the display control unit 30 returns to step S200 and continues book selection. When the Selection Complete button 4304 on the book selection screen 4300 is operated, the transmission unit 34 proceeds to step S218 and transmits a search request for the online library catalog including all ISBN codes displayed on the book selection screen 4300 to the server device 10.

[0154] When the server device 10 receives a search request for an online library catalog containing an ISBN code, it searches the online library catalog for books corresponding to the ISBN code received from the user terminal 16, as described in the first embodiment, and transmits the search results to the user terminal 16.

[0155] In step S220, the receiving unit 36 ​​of the user terminal 16 receives the search results for the online library catalog search request sent in step S218. In step S222, the display control unit 30 displays the search result screen 4400 or 4500 based on the received search results.

[0156] If the search results show that all of the ISBN codes displayed on the book selection screen 4300 are in the library's collection, the display control unit 30 displays a search result screen 4400. The search result screen 4400 displays the book titles of all of the books whose ISBN codes are displayed on the book selection screen 4300, and information indicating that the books are included in the library's collection.

[0157] Furthermore, if the search result shows that at least one book with the ISBN code displayed on the book selection screen 4300 is not in stock, the display control unit 30 displays a search result screen 4500. The search result screen 4500 is an example of a second screen.

[0158] The search result screen 4500 displays the book names of books with ISBN codes displayed on the book selection screen 4300 that are not in the library's collection, information indicating that the book is not included in the library's collection, and a purchase request button 4502. The purchase request button 4502 on the book selection screen 4300 is a button that accepts an operation from the user to request the purchase of a book whose book name is displayed on the search result screen 4500.

[0159] In step S224, the determination unit 40 determines whether or not the user has operated the purchase request button 4502. If the user has operated the purchase request button 4502, the process proceeds to step S226, and the transmission unit 34 transmits to the server device 10 information indicating a desire to purchase the book having the book title displayed on the search result screen 4500.

[0160] As described in the first embodiment, the server device 10, which has received information on a book purchase request from the user terminal 16, searches to see if the book for which the purchase request information has been received is included in the purchase wish list. The server device 10 references the purchase wish list and determines whether a purchase request has been received in the past for the book for which the purchase request information has been received from the user terminal 16. If a purchase request has been received in the past, the server device 10 generates a result indicating that the purchase request has already been received and transmits it to the user terminal 16. If a purchase request has not been received in the past, the server device 10 generates a result indicating that the purchase request information has been received and transmits it to the user terminal 16. If a purchase request has not been received in the past, the server device 10 registers the book for which the purchase request information has been received in the purchase wish list.

[0161] In step S228, the receiving unit 36 ​​of the user terminal 16 receives the purchase request results transmitted to the server device 10. In step S230, the display control unit 30 of the user terminal 16 refers to the received purchase request results and displays the purchase request result screen 4600 or 4700.

[0162] If the received purchase request result indicates that the purchase request information has been accepted, the display control unit 30 displays a purchase request result screen 4600. The purchase request result screen 4600 displays a message indicating that the purchase request for the book whose title is displayed on the search result screen 4500 has been accepted.

[0163] Furthermore, if the received purchase request result indicates that the purchase request has already been accepted, the display control unit 30 displays a purchase request result screen 4700. The purchase request result screen 4700 displays a message that the purchase request for the book whose title is displayed on the search result screen 4500 has already been accepted.

[0164] In this way, according to the information processing system 1 of the second embodiment, when a user has multiple books that he or she would like to request from a library to purchase, the user can easily check whether the multiple books are in the library's collection.

[0165] Furthermore, according to the information processing system 1 of this embodiment, if a user has multiple books that he or she wishes to request the library to purchase, and the library has not previously requested the user to purchase the multiple books that the user wishes to purchase, the user can easily make a request to the library to purchase the multiple books all at once.
