In this case, a “next document” button is displayed at the bottom of the screen of FIG. 12, and the number of documents from which the tag information 33 such as 1/2 is read is displayed at the top of the screen of FIG. .

On the search screen 1200, the user selects a search category 1203 ("reference document search", "keyword search", "designated location search", etc.), a search target reference document 1204 ("collection only in the library", "other than collections"). Keyword search range 1205 ("book title only", "table of contents only", "full text", "text and references", etc.), keyword 1206, search condition 1207 ("page range of documents", " Chapter ”,“ Literature section ”,“ Publication date of reference ”,“ Language of reference ”, etc.), numerical value 1208 of search conditions, etc. are input as appropriate.
When the user presses the “Search” button 1209, the search terminal device 3 advances the process to Step 803.

  In step 801 and step 802, if the original document 13 cannot be brought close to the tag reader 11 or the tag information cannot be read, the search terminal device 3 replaces the search screen 1200 for detailed document search shown in FIG. A search screen 1300 for general-purpose document search shown in FIG. 13 is displayed. In this case, the user appropriately inputs a book name 1301, an author name 1302, a keyword 1306, and the like on the search screen 1300. When the user presses “Search” button 1309, search terminal apparatus 3 advances the process to step 803.

In steps 803 to 804, the search terminal device 3 transmits the search conditions specified on the search screen 1200 or the search screen 1300 to the library server 5 and enters a waiting state for receiving list information.
In step 821, the library server 5 receives the search condition from the search terminal device 3, and holds it in the work area of the RAM.
In step 822, the library server 5 refers to the collection DB 19 of the storage unit 17 and performs a collection search based on the search conditions (keyword, page range, chapter, section, issue date, language, search range, etc.).

If a keyword is specified in the collection search in step 822, the library server 5 extracts from the collection DB 19 not only the search by the keyword but also the lending status (lending, lending available, reservation availability, etc.) of the book hit with the keyword. And stored in the work area of the RAM.
When no keyword is specified in the collection search in step 822, for example, when the ISBN of a specific book is read from the IC tag 15 of the original document 13, the library server 5 reads the book lent together with the specific book. Is extracted from the collection DB 19 and stored in the work area of the RAM.

In step 823 to step 824, when ISBN is designated, the library server 5 determines the ISBN, keywords, other inquiry keys (issue date, etc.), ISBN of documents often borrowed together (collection of step 822). The search result) is transferred to the book information server 7.
In step 823, if ISBN is not designated, the library server 5 transfers the keyword and other inquiry keys (page range, etc.) to the book information server 7.
In steps 824 to 825, the library server 5 enters a state of waiting for reception of document information from the book information server 7.

In step 841, the book information server 7 receives the inquiry key sent from the library server 5 and stores it in the work area of the RAM.
In step 842, the book information server 7 refers to the book DB 23 of the storage unit 21 and performs a document search based on the received inquiry key. The details of the document search will be described later with reference to FIG.
In addition to the bibliographic items, the book DB 23 stores text data of table of contents information, text data of the whole body text, image data such as photographs, illustrations, and illustrations.
In step 843, the book information server 7 transmits document information that is a result of the document search to the library server 5.

In step 825, the library server 5 stores the literature information received from the book information server 7 in the work area of the RAM.
In step 826, the library server 5 merges the collection search result (step 822) and the document search result (step 842) stored in the RAM work area to generate search result list information. To the search terminal device 3.
Here, merging a book search result and a document search result means that a book search similar to step 822 is performed using the ISBN or document of the hit document included in the document search result as a key, and the hit document of the document search is found. This means that whether or not it is a collection, and if it is a collection, the result of whether it can be lent out is extracted and merged with the result of the collection search in step 822. Thereafter, in step 827 to step 828, the selection information reception wait state is entered.
In step 805, the search terminal device 3 receives list information from the library server 5.

In step 806 to step 808, when the search condition 1207 is specified on the search screen 1200 for detailed document search in step 802, the search terminal device 3 displays a list of searched references on the list screen 1400 shown in FIG. Then, the contents input on the list screen 1400 are transmitted to the library server 5 as selection information.
As shown in FIG. 14, on the list screen 1400, the document name 1401, the document classification 1402, the lending availability 1403, the purchase availability 1404 (including the purchase of books, the availability of all / partial purchase of electronic data), lending / A reservation 1405, purchase 1406, and the like are displayed.

In Steps 810 to 813, when there is a purchase request (Yes in Step 810), the search terminal device 3 waits for purchase screen data from the library server 5 (Step 811) and displays the purchase screen when receiving the purchase screen data. The contents are displayed (Yes in step 812), and the content input on the purchase screen is transmitted to the library server 5 as purchase information (step 813).

In step 806 to step 808, when the search condition 1307 is specified on the search screen 1300 for general-purpose document search in step 802, the search terminal device 3 displays a list of searched references on the list screen 1500 shown in FIG. Then, the contents input on the list screen 1500 are transmitted to the library server 5 as selection information.
As shown in FIG. 15, on the list screen 1500, the document name 1501, the document classification 1502, the lending availability 1503, the purchase availability 1504 (including purchase of books, availability of all / partial purchase of electronic data), lending / A reservation 1505, purchase 1506, and the like are displayed.

For books that can be lent, a check is put in the column of lending / reservation 1505, and when an application button 1508 is pressed (Yes in step 807), a lending procedure is performed (steps 829 to 830).
For books that are currently lent out, a check is put in the column of lending / reservation 1505, and when an application button 1508 is pressed (Yes in step 807), a reservation procedure is performed (steps 831 to 832).
For a book that can be purchased, if a check is put in the column of purchase 1506 and the application button 1508 is pressed (Yes in Step 807), the purchase procedure is performed via the purchase screen 1600 shown in FIG. Step 813, Step 833 to Step 835).
In Steps 810 to 813, when there is a purchase request (Yes in Step 810), the search terminal device 3 waits for purchase screen data from the library server 5 (Step 811) and displays the purchase screen when receiving the purchase screen data. The contents are displayed (Yes in step 812), and the content input on the purchase screen is transmitted to the library server 5 as purchase information (step 813).

In step 807 and step 809, when the “previous screen” button 1407 or the “previous screen” button 1507 is pressed on the list screen 1400 or the list screen 1500 (No in step 807, Yes in step 809), the search terminal The apparatus 3 repeats the processing from step 802.
In step 807 and step 808, a check mark is entered in the column of “lending / reservation” 1405, “purchase” 1406, or “lending / reservation” 1505, “purchase” 1506 on the list screen 1400 or the list screen 1500. When the “apply” button 1408 or the “apply” button 1508 is pressed in the state (Yes in step 807), the search terminal device 3 uses the contents input on the list screen 1400 or the list screen 1500 as selection information and the library server 5 (Step 808).

In Step 828 to Step 835, when the library server 5 receives the selection information from the search terminal device 3 (Yes in Step 828), the lending process (Step 829 to Step 830) and the reservation process for each document according to the check mark. (Step 831 to Step 832) and purchase processing (Step 833 to Step 835) are appropriately executed.
In step 844, upon receiving a purchase request from the library server 5, the book information server 7 performs order processing.
Details of the purchase process (steps 833 to 835) will be described later with reference to FIG.
As for order processing, instead of the book information server 7, an order processing server for order processing may be provided separately.

In step 836, the library server 5 determines whether or not all documents on the list screen 1400 or the list screen 1500 have been processed.
When the library server 5 completes the processing for all the documents (Yes in Step 836), it transmits the processing result to the search terminal device 3 and ends the processing (Step 837). The search terminal device 3 displays the processing result. Display (steps 814 to 815), and repeat the processing from step 402.
If the library server 5 has not finished processing all the documents (No in step 836), the library server 5 repeats the processing from step 829.

(3-2. When the tag information 33 holds reference information)
FIG. 9 is a flowchart showing the operation of the document inquiry system 1.
FIG. 9 shows processing in the case where the reference information related to the original document 13 is held in the tag information 33 of the IC tag 15 incorporated in or pasted in the original document 13.

In FIG. 9, steps 901 to 915 are executed under the control of the CPU of the search terminal apparatus 3, steps 921 to 934 are executed under the control of the CPU of the library server 5, and step 941 is the book information server 7. It is executed under the control of the CPU.
In step 901, when a user (library user, library staff, etc.) brings the original document 13 such as a book close to the tag reader 11 connected to the search terminal device 3, the tag reader 11 is incorporated or attached to the original document 13. The tag information 33 held by the IC tag 15 is read and transferred to the search terminal device 3.

  In the process shown in FIG. 8, the IC tag 15 has been described as holding at least the ISBN of the original document 13 and the URL or IP address for searching in the book information server 7, but in the process shown in FIG. In addition, the ISBN of the reference related to the original document 13 is stored.

In step 903, the search terminal device 3 transmits the original document 13 and the ISBN of the reference document to the library server 5 together with the search condition specified on the search screen 1200 or the search screen 1300.
In step 922, the library server 5 collectively performs a collection search based on the original document 13 sent from the search terminal device 3 and the ISBN of the reference document, and based on the frequency of borrowing together with the original document 13 (for example, 5), the reference literature can be extracted from the collection DB 19 of the storage unit 17.
Since the IC tag 15 holds reference document information related to the original document 13, processing corresponding to steps 823 to 825 and steps 841 to 843 in FIG. 8 does not exist in FIG.
9 is substantially the same as the process shown in FIG. 8 and will not be described.

(3-3. Details of document search processing)
FIG. 10 is a flowchart showing details of the document search process (FIG. 8: step 842) in the book information server 7.

  The book information server 7 reads the inquiry key received from the library server 5 and stored in the work area of the RAM (step 1001), determines whether or not the ISBN designation is included in the inquiry key, and if the ISBN is included (step 1002). Yes), the processing of step 1003 to step 1013 is performed, and when the ISBN designation is not included (No in step 1002), the processing of step 1021 to step 1028 is performed.

When ISBN is included in the inquiry key (Yes in step 1002) and further keyword specification is included (Yes in step 1003), the book information server 7 refers to the book DB 23 of the storage unit 21, and based on the keyword, A full text search is performed for references that are often ordered together (step 1004).
The book information server 7 determines whether or not the number of hits in the full-text search exceeds a predetermined number (for example, 10), and if it does not reach the predetermined number (No in step 1005), the concept tree 1700 in the storage unit 21. Referring to the keyword, a full-text search (concept search) is performed again using the upper concept or lower concept of the keyword (step 1006). The concept search (step 1006) will be described later with reference to FIG.

  The book information server 7 totals the hit numbers of the full-text search or concept search by keyword, calculates a score based on the hit number and keyword distribution status (step 1007), and creates a hit list (step 1008).

In addition, when the hit location of a keyword or a concept is in the table of contents, the score becomes high when a predetermined ratio or more (for example, 50% or more) of hit locations is concentrated in a specific chapter or section.
In addition, the book information server 7 creates a hit list by placing the documents that are frequently ordered together with the original document 13 and having a large number of keyword hits at the top.
The book information server 7 has, for example, a hit list having a rank, the number of loans, a document name, ISBN, a keyword hit count, and a score for a document that is frequently ordered together with the original document 13 (for example, the top five documents). Or a hit list having ranking, score, keyword hit count, document name, ISBN, and loan count for documents with high scores (for example, top 5).

  If ISBN is included in the inquiry key (Yes in step 1002) and no keyword is specified (No in step 1003), or if a hit list is created (step 1008), the process proceeds to step 1009.

  When there is a reference specification (Yes in Step 1009), the book information server 7 matches the references that are often borrowed together with the reference of the original reference 13 to narrow down the reference (Step 1010), and has a keyword specification. In the case (when the process proceeds from step 1008 to step 1009), full text search, concept search, hit count, and score aggregation are performed by the same processes as in steps 1004 to 1007 (step 1011).

The book information server 7 generates a hit list of documents that are included in the reference document list of the book designated by ISBN and often ordered together (step 1012).
For example, the book information server 7 ranks, borrows, document name, ISBN, keyword hit count and score (keyword designation is high) for documents that are frequently ordered together with the original document 13 (for example, the top five). A list of hits (if any), and on the premise that there is a keyword specification, for documents with a large number of keyword hits (for example, the top five), ranking, keyword hit count, document name, ISBN, A reference list having a loan count and a score is generated (step 1012), and the process is terminated.

When ISBN is specified, no keyword is specified, and no reference is specified (Yes in Step 1002, No in Step 1003, No in Step 1009), the book information server 7 refers to the book DB 23 in the storage unit 21, Text information and the like of the text of the document indicated by ISBN are extracted (step 1013).
The text information or the like can be used for downloading, printing, etc. to provide a copying service or the like.

If ISBN is not included in the inquiry key (No in step 1002) and further keyword specification is included (Yes in step 1021), the book information server 7 performs the same processing as in steps 1004 to 1007 described above (step 1022-step 1025), the original data of the hit list including the ranking, the score, the number of keyword hits, the document name, and the ISBN is created, and the score is classified according to the type of the document according to the purpose of use of the book from the original data of the hit list. A document with an appropriate number of upper ranks is selected (step 1026), and a hit list is created (step 1028).
Note that the purpose of use of the book is specified in the column “use purpose of book” 1310 of the search screen 1300. Further, FIG. 18 will be described later regarding the hit list creation processing corresponding to the purpose of use of the book.

  When ISBN is not included in the inquiry key (No in Step 1002) and no keyword is specified (No in Step 1021), the book information server 7 searches based on the bibliographic items such as the author name and the date of issue. Is executed (step 1027). A hit list including the document name, ISBN, date of issue, etc. is generated (step 1028).

(3-3-1. Concept tree 1700)
FIG. 17 is a diagram illustrating an aspect of the concept tree 1700.
A concept tree 1700 shown in FIG. 17 forms a tree by connecting words and phrases of a higher concept with branches.
When the book information server 7 does not reach the predetermined number of hits by the search using the specified keyword, the book information server 7 sequentially searches the concept tree 1700 using the upper concept or the lower concept until the predetermined hit number is reached (see FIG. 10: Step 1006, Step 1024).
For example, the book information server 7 searches for a designated keyword “line” 1701 and, if the number of hits is less than a predetermined number of hits, searches for “wired line” 1702 and “wireless line” 1703, which are subordinate concepts.

(3-3-2. Hit Count List 1800 by Purpose)
FIG. 18 is a diagram showing an aspect of the hit number list 1800 for each purpose.
As shown in FIG. 18, the hit-by-purpose list 1800 has fields of a book usage purpose 1801 and a group 1802 to a group 1805.
A group 1802 to a group 1805 indicate document classifications (eg, “book”, “paper journal”, etc.) and numbers included in the hit list (eg, “10”, “20”, etc.).
The book information server 7 refers to the purpose-specific hit count list 1800 held in the storage unit 21 and sorts the documents according to the document usage according to the purpose of use of the book specified in the “book use purpose” column 1310 of the search screen 1300. A document with an appropriate number of high scores is selected (FIG. 10: Step 1026), and a hit list is created by sorting (FIG. 10: Step 1028).
In addition, regarding the display, the first group to the fourth group may be displayed separated by spaces or lines.

(3-4. Details of purchase processing)
FIG. 11 is a flowchart showing the operation of the library server 5 in the purchase process (FIG. 8: step 835, FIG. 9: step 932).
Note that the processing shown in FIG. 11 is executed under the control of the CPU of the library server 5.

  When the library server 5 transmits a purchase screen to the search terminal device 3 (FIG. 8: step 834, FIG. 9: step 931), the search terminal device 3 displays a purchase screen 1600 as shown in FIG. When a predetermined item is input to 1600, it is transmitted as purchase information to the library server 5 (FIG. 8: step 813, FIG. 9: step 913), and the library server 5 performs a purchase process (FIG. 11).

In the purchase screen 1600 of FIG. 16, “category” 1601 is a field for designating a unit of purchase and the like, for example, “book (whole)”, “book (part / paper)”, “book (part / data)”. ", Etc." can be selected. When "Part" is designated, "Chapter" 1602, "Page", etc. can be designated. In the case of partial purchase, when a “Purchase” button 1603 is pressed, a confirmation pop-up screen displaying the partial purchase price is displayed.
In the “personal information registration” 1604, a name, a telephone number, an address, a payment method, a number, etc. can be registered excluding the “card expiration date” 1605 and the “card PIN” 1606.

  If the purchase budget (maximum amount) and delivery date (acquisition date) are specified in the search condition specification, the library server 5 satisfies them, and if there are a plurality of suppliers, compare them to determine the delivery date. Perform processing to purchase from the lowest price supplier within the range of satisfaction. Then, the library server 5 transmits the purchase information to the order destination such as the book information server 7 (FIG. 8: Step 844, FIG. 9: Step 941).

  The library server 5 has a predetermined URL indicating the book information server 7, data in a predetermined format (eg, data with a tag such as XML), order number, ISBN, quantity, new book / used category, applicant name, library The price storage period inquiry data describing the reply destination information (IP address, port number, reply user ID, password, etc.) to the server is transmitted (step 1101).

  When a plurality of book information servers 7 that sell the specified documents are registered, the library server 5 transmits the price storage period inquiry data to each book information server once (total number of times), Add the number of records equal to the number sent to the order work file. When there are a plurality of types of documents to be purchased, these processes are repeated for the number of types to be purchased (a plurality of purchases of the same document are processed in one transmission).

The order work file includes items such as order number, ISBN, quantity, new / used category, applicant name, price category, purchase category, inquiry transmission time, order transmission time, book seller name, delivery date, unit price, price, etc. Is memorized.
As the price category, “0” is normally stored, and “1” is stored in the record of the lowest unit price with the same order number.
As the purchase category, “0” is normally stored, “1” is stored in the record to be purchased, and “2” is stored when the purchase becomes impossible due to out of stock.
The transmission time stores the time when the price storage period inquiry information and the order information are transmitted.
As the unit price, “999999 (maximum value)” is initially input, and when the answer is received, the received unit price is stored. The book information server ID may be stored instead of the book seller name.

  It should be noted that a predetermined title (for example, “book purchase application”), a predetermined text format (for example, “order number” on the first line, “ “ISBN”, “quantity” on the third line, “new book / used category” on the fourth line, and “name of applicant” on the fifth line) may be transmitted.

When the book information server 7 receives the price storage period inquiry data, the answer information including the order number, ISBN, quantity, new book / used category, delivery date, unit price, price (unit price x quantity), applicant name, book seller name, etc. Is transmitted based on the reply destination information of the library server 5.
When receiving the reply information, the library server 5 updates the ordering work file based on the reply information using the order number and the book seller name as keys. This reception process is executed by a process different from the flowchart shown in FIG.

  The library server 5 refers to the order work file, and determines whether or not a predetermined time (for example, 30 minutes) has elapsed since the price storage period inquiry data was first transmitted for the specific order number (step 1102). If the predetermined time has elapsed (Yes in step 1102), the process proceeds to step 1112. If the predetermined time has not elapsed (No in step 1102), the process proceeds to step 1103.

The library server 5 waits to receive reply information (price, delivery date, etc.) from the book information server 7 (step 1103), and when a certain time (for example, 30 seconds) elapses, the process proceeds to step 1104. .
The library server 5 refers to the order work file and determines whether or not response information has been received (step 1104). If the response information is received (Yes in step 1104), the process proceeds to step 1105. If the answer information has not been received (No in step 1104), the process returns to step 1102.

  The library server 5 compares the delivery date of the response information with the delivery date in the search condition information of the order number stored in the work area of its own RAM (step 1105).

The library server 5 determines that the delivery date is satisfied when the delivery date of the response information is equal to or earlier than the delivery date of the search condition information of the order number (Yes in step 1106). The library server 5 determines that the delivery date is satisfied when the delivery date is not specified in the search condition information stored in the work area of its own RAM (Yes in step 1106).
If the delivery date is satisfied (Yes in Step 1106), the library server 5 advances the process to Step 1107. If the delivery date is not satisfied (No in Step 1106), the library server 5 returns the process to Step 1104.

The library server 5 refers to the order work file using the order number as a key, and compares the price of the response information received this time with each record in the order work file using the same order number as a key (step 1107).
When the unit price of the response information this time is lower than the price of other records of the same order number stored in the ordering work file (Yes in Step 1108), the library server 5 advances the process to Step 1109, and if it is higher or equal (No in step 1108), the process returns to step 1103.

  The library server 5 updates the price category of the record of the ordering work file corresponding to the current answer information of the order number to “1” (step 1109), and when a predetermined time elapses without receiving the answer information. (Step 1103, No in Step 1104, Yes in Step 1102), the order information is transmitted to the transmission source of the response information identified by the order information and price category = “1” (Step 1111).

The order information is obtained by adding a payment method (payment category, card number, etc.) to the inquiry information. The book information server 7 that has received the order information, based on the reply destination information of the library server 5, orders number, ISBN, quantity, new book / used category, delivery date, unit price, price (unit price × quantity), applicant name, Response information including the name of the book seller, purchase permission / inhibition category (order OK = “1”, order NG = “2”), etc. is transmitted.
Upon receiving the response information, the library server 5 sets the purchase classification of the order work file to “1 (order OK)” or “2 (order NG)” based on the response information using the order number and book seller name as a key. Update. This reception process is executed by a process different from the flowchart of FIG.

The library server 5 waits to receive confirmation information from the book information server 7 (step 1112), and when a certain time (for example, 30 seconds) has elapsed, the processing proceeds to step 1113.
In step 1113, the library server 5 refers to the ordering work file, determines whether confirmation information has been received, and receives confirmation information (purchase category = “1” or “2”) (Yes in step 1113). , The process proceeds to step 1114.
If reply information has not been received (purchase category = “0”) (No in step 1113), the process proceeds to step 1119.

  The library server 5 determines whether or not an order NG (purchase category = “2”) has been received based on the confirmation information for the order number (step 1114). If received (Yes in step 1114), the process proceeds to step 1118. If not received (purchase category = “1”) (No in step 1114), the process proceeds to step 1115.

The library server 5 deletes records other than purchase classification = “1” with the same order number (step 1115).
When a plurality of types of documents are ordered, the library server 5 determines whether all the documents are accepted, and if all documents are OK (Yes in step 1116), the process proceeds to step 1117. If all documents are not OK (No at step 1116), the process proceeds to step 1119.
In step 1117, a message to the effect that purchase processing of all documents has been completed is transmitted to the library terminal.

  In step 1118, the library server 5 advances the process to step 1120 when a predetermined time (for example, 10 minutes after the order information is transmitted) (Yes in step 1118), and proceeds to step 1120 if not (No in step 1118). ), The process returns to step 1110, and the price category of the record with the next lowest unit price after the order information is updated to “1” (step 1110).

In step 1119, the library server 5 advances the process to step 1120 when a predetermined time (for example, 10 minutes after the order information is transmitted) (Yes in step 1119), and proceeds to step 1120 if not (No in step 1119). ), And returns to Step 1112.
In step 1120, the library server 5 transmits a message to the library terminal that purchase processing of some documents is incomplete (step 1120).

(4. Other)
Various embodiments can be adopted for the above-described literature inquiry system according to the present invention.

(4-1.)
An IC tag is built in each book, and the ISBN of the book and the reference link to the reference list file of the book are stored in each IC tag. Accessing a bibliography file from a reference link returns the ISBN (s) of the bibliography. Using the returned ISBN as a key, the library collection DB of the library is searched, and the presence or absence of the collection, whether or not the book is being rented, and the collection position of the book are displayed on the search terminal device. For books that can be lent out of the collection, you can easily make temporary reservations by placing a check mark. In this case, the temporary reservation may be deleted if it is not brought to the lending counter within 30 minutes. If it is not a collection, the presence / absence of the collection at the affiliated library and the availability of the loan are displayed. Books that are not in the collections of affiliated libraries will display a link to the publisher's purchase page. Purchases can also be made with electronic data (including partial book data).

(4-2.)
An IC tag is incorporated in each book, and a reference link to the full text DB of the book is stored in each IC tag. When the user inputs a keyword indicating a theme from a search terminal device such as a library, the full text DB is searched using the keyword input from the reference link as a key. There is a high possibility that a document with a high number of hits will be a basic document among books that have hit keywords. In addition, books and magazines that have a relatively large number of hits (for example, within the top 10) and that have a new issue date than the basic document may become supplementary documents that can confirm relatively new information. Is expensive. Furthermore, a document that is frequently lent together with the book in the past and that is introduced as a reference document for the book is likely to be a useful document. These documents can be easily searched and extracted.

(4-3.)
If the retrieved reference is not immediately available due to reasons such as not being in the library during lending, the library can check the collection of the affiliated library nearby and whether or not it can be rented and display the results or purchase the library. Search whether it is in time for the timing (decision-making period, arrangement period), or try to purchase books in the order of "Search for inventory at nearby bookstores" → "Intermediate inventory" → "Publisher purchase site" Also good. Also, download of electronic book data (all books, only a part, etc.) may be specified on the purchase site of the publisher. In this case, it is desirable to put a digital watermark for each purchaser.

(5. Effects, etc.)
In the document inquiry system according to the present invention, the reference retrieval process is performed based on the tag information read from the IC tag attached to the original document, the search condition input separately, etc. And the desired reference can be reached quickly and accurately.
In addition to reading the identifier of the original document in addition to the identifier of the original document from the IC tag, by performing a search process in the collection database collectively using the identifier of the original document and the identifier of the reference document, It is not always necessary to access the book information server when searching and inquiring a reference document, and the processing load, search time, etc. can be reduced.

  The preferred embodiments of the document inquiry system, the library server, the book information server, and the like according to the present invention have been described above with reference to the accompanying drawings, but the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes or modifications can be conceived within the scope of the technical idea disclosed in the present application, and these are naturally within the technical scope of the present invention. Understood.
