On January 1, 2007, the book industry began using 13 digit ISBNs to identify all books in the supply chain. The U.S. ISBN Agency notes that this change was effected to "expand the numbering capacity of the ISBN system and alleviate numbering shortages in certain areas of the world," and "to fully align the numbering system for books with the global EAN.UCC identification system that is widely used to identify most other consumer goods worldwide."
An ISBN-13 differs from an ISBN-10 through the inclusion of a three-digit prefix (978 or 979) and a different check digit (final digit) at the end. Conversion tools are available to convert ISBN-10s to ISBN-13s (and vice versa) and to calculate an ISBN's check digit. Please note, however, that ISBN-13s beginning with the prefix 979 have no ISBN-10 counterparts.
The Library of Congress Online Catalog automatically converts between ISBN-10s and ISBN-13s, ensuring that any ISBN search will check for both an ISBN-10 and an ISBN-13. For example, if a catalog record includes only an ISBN-10, a search for the equivalent ISBN-13 will retrieve the record.
Is there an International Standard Book Number (ISBN) database I can use that will allow me to extract bibliographic data for books and import them into a local database?
Several extensive book databases allow users to retrieve bibliographic information based on an ISBN search. None of these databases is comprehensive, however. Examples of proprietary databases that allow retrieval of bibliographic information for books based on ISBN are the subscription database Books in Print and the database freely available online through the commercial vendor Amazon.com (see its Advanced Search page). To see if it is possible to configure the information in these databases for your needs, and to obtain permission to do so, you will need to contact and obtain the permission of the vendor.
While the Library of Congress generally cannot provide technical support services for individuals creating their own catalogs or databases, the Library of Congress online catalog allows users to search for and retrieve catalog records based on ISBNs. If you would like to use the information in the catalog to develop a Web-based application that captures bibliographic information based on an item's ISBN, the Library supports a Web service that allows users to retrieve catalog records in XML. In order to take advantage of this service, known as SRU (Search/Retrieval via URL), users must have the ability to display the XML data in the format they desire. Below are some examples of SRU requests that retrieve the same record from the Library's catalog (via its Z39.50 interface). The final two examples make use of XSLT style sheets created by the Library. Users can also develop their own style sheets and retrieve the raw XML records using requests similar to the first one listed below.
