HathiTrust Digital Library

This database is freely available to the general public via the Internet.


Special Note: For detailed guidance on use, consult: Help -- Using the Digital Library and A User's Guide to HathiTrust .  

Nearly 14 scanned volumes (as of 10/27/2015), all described by precise metadata, are currently in the HathiTrust database. Over 6.3 million are in the public domain.  For Statistics and Visualizations of holdings visit As explained on its Web site: the Trust is "a partnership of major research institutions and libraries working to ensure that the cultural record is preserved and accessible long into the future" (Hathi is the Hindi word for elephant - and an elephant NEVER forgets!) and their mission is "to contribute to the common good by collecting, organizing, preserving, communicating, and sharing the record of human knowledge." Over 100 research institutions and 4 consortia or state systems are partners (as of 10/27/2015).  While Google scans are a critical component of the corpus, it is much more. Unique material is in both Google and HathiTrust and there are topical collections reflecting recent and focused institutional scanning efforts. Google scans that are included have been reviewed for quality of scan and have been assigned full and accurate metadata. In fact, HathiTrust bibliographic records are freely available to institutions for loading in their catalogs and you'll see HathiTrust as well as Google Books availability indicated in our catalog.  Do a keyword search for "hathitrust" (one word) in WorldCat to retrieve HathiTrust records.  HathiTrust is stylistically one word as explained in the organization's style sheet:

Works in the public domain (generally pre-1923) in HathiTrust are freely available to all researchers and may be read and searched in their entirety. Works in copyright may be searched in "limited" mode, with only the page number and number of hits given. In the future, in partnership with Indiana University and the University of Illinois at Urbana-Champaign, text-mining projects similar to Google's Ngram Viewer will be supported. Use HathiTrust and Google Books in combination. The "readers" and "search engines" of course, are different.

Like Google Books, more than books are in the database. The HathiTrust Digital Library contained, as of 16 May 2011, 8,724,587 volumes or 4,774,586 book titles and 211,665 serial titles.

All public domain titles not digitzed by Google and in the HathiTrust Digital Library are available for full PDF download. Texts scanned by Google are only available for full PDF download  from within the HathiTrust Digital Library to partners within the United States.  Therefore, there are two categories of Google scans; although both categories are viewable.  Over 100,000 Internet Archive digitzed volumes are available.  In addition, there are works that rights holders have opened access to in HathiTrust.  These are viewable and searchable to all; but if digitzed by Google, full download in only available with a Creative Commons license.  Print on demand is available worldwide with permission.
