Welcome to HathiTrust!

Founded in 2008, HathiTrust is a not-for-profit collaborative of academic and research libraries preserving 17+ million digitized items. HathiTrust offers reading access to the fullest extent allowable by U.S. copyright law, computational access to the entire corpus for scholarly research, and other emerging services based on the combined collection. HathiTrust members steward the collection — the largest set of digitized books managed by academic and research libraries — under the aims of scholarly, not corporate, interests.

HathiTrust advances its mission and goals through services and programs: 

HathiTrust Digital Library preserves and provides lawful access to the 17+ million digitized items. The Emergency Temporary Access Service permits temporary, emergency access to the collection for member libraries during service disruptions caused by the glocal pandemic.
HathiTrust Research Center offers services that support use of the HathiTrust corpus as a dataset for analysis via text and data mining research.
Shared Print Program develops a distributed, shared network of print collections with collective print retention.
U.S. Federal Documents Program expands access to and preserve U.S. federal publications. 
Copyright Review Program review team finds and opens public domain materials in the U.S. and around the world.
