Data from the collection can help you make collection decisions, integrate items locally, or support researchers in more robust research inquiries.</p> <h2><strong>Notes on Working with HathiTrust Data</strong></h2> <p>While working with HathiTrust bibliographic metadata or digital content, it may helpful to keep the following in mind.</p> <p>The HathiTrust collection is not static. Works get added to the collection every day, and sometimes a digital item may be updated with a new version. Bibliographic records can be updated when contributors send us corrections. Copyright and access statuses may change as items undergo copyright review or we receive permissions agreements from copyright holders.</p> <p>The HathiTrust collection comprises works from <a href="https://www.hathitrust.org/member-libraries/member-list/">more than 60 different libraries</a> located in the United States and around the world. Bibliographic records represent many different cataloging practices and may even be in different languages.</p> <p>We work closely with our contributing libraries to try to correct errors in bibliographic records and digital content (including poor OCR). Users can notify us about errors using the “feedback” link in the header or footer of most pages. Because the originating library or vendor may need to make the change on their end, it may take a while for corrections to be made in HathiTrust.</p> </div> <div class="pbs"> <div class="pb"> <div class="pb-contents"><p>This API can provide you with a limited number of brief or full bibliographic records for real-time queries. </p> </div> <div class="pb-link"> <a href="https://www.hathitrust.org/member-libraries/resources-for-librarians/data-resources/bibliographic-api/" class="link-arrow"><span>Bibliographic API</span></a> </div> </div> <div class="pb"> <div class="pb-contents"><p>Use this option to retrieve metadata from full-view items in MARC21 or unqualified Dublin Core formats.</p> </div> <div class="pb-link"> <a href="https://www.hathitrust.org/member-libraries/resources-for-librarians/data-resources/oai-feed/" class="link-arrow"><span>OAI Feed</span></a> </div> </div> <div class="pb"> <div class="pb-contents"><p>Tab-limited files of metadata describing all works in the HathiTrust collection may be used for collection management, record retrieval, or building links to HathiTrust works.</p> </div> <div class="pb-link"> <a href="https://www.hathitrust.org/member-libraries/resources-for-librarians/data-resources/hathifiles/" class="link-arrow"><span>hathifiles</span></a> </div> </div> <div class="pb"> <div class="pb-contents"><p>A tab-delimited file containing U.S. copyright renewal registration numbers in connection with a HathiTrust volume identifier is available for download.</p> </div> <div class="pb-link"> <a href="https://www.hathitrust.org/member-libraries/resources-for-librarians/data-resources/renewal-id-file/" class="link-arrow"><span>Renewal ID File</span></a> </div> </div> <div class="pb"> <div class="pb-contents"><p>For in-depth research and exploration of the collection, you can request a custom dataset or use a pre-built dataset from the HathiTrust Research Center.</p> </div> <div class="pb-link"> <a href="https://www.hathitrust.org/member-libraries/resources-for-librarians/data-resources/research-datasets/" class="link-arrow"><span>Research Datasets</span></a> </div> </div> </div> <div class="mainplain"><h2><strong>HathiTrust Data in Discovery Products</strong></h2> <p>HathiTrust publicly-available data is consumed into a number of different vendor discovery products, including the following: Summon, EBSCO Discovery Services, Ex Libris Primo, OCLC WorldCat Discovery, Innovative Interfaces Inc Encore. In addition, a number of knowledge bases include HathiTrust data, including EBSCO’s Knowledge Base and OCLC’s WorldShare Collection Manager. Other vendor products may also include HathiTrust data.</p> <p>Quality and accuracy of HathiTrust data in vendor products may vary.
