Name, Mission, and History

 

What does Hathi mean?

Hathi (pronounced hah-tee) is the Hindi word for elephant, known for its long memory, strength, and wisdom.  Trust is an essential value of research libraries and one of their greatest assets. The terms together convey the benefits researchers can expect from a collaborative digital repository focused on preserving and sustaining our common scholarly inheritance.

Mission

The mission of HathiTrust is to contribute to research, scholarship, and the common good by collaboratively collecting, organizing, preserving, communicating, and sharing the record of human knowledge.

History

HathiTrust began in 2008 as a collaboration of the universities of the Committee on Institutional Cooperation and the University of California system to establish a repository to archive and share their digitized collections, though it has quickly expanded to include a large and growing partnership community, which Wesleyan joined in 2016.
