The HathiTrust Digital Library is a large-scale digital preservation repository that was launched by a partnership of major research libraries in 2008. There are currently more than two dozen partners. Partnership is open to research institutions worldwide. The initial focus of the partnership is on preserving and providing access to book and journal content digitized from partner collections through a number of means, including digitization by Google, the Internet Archive, and through local initiatives.
The partners aim to build a comprehensive archive of published literature from around the world and develop shared strategies for managing and developing their digital and print holdings in a collaborative way. The primary community that HathiTrust serves are the members (faculty, students, and users) of its partners libraries, but the materials in HathiTrust are available to all to the extent permitted by law and contracts, providing the published record as a public good to users around the world.
