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.
