The Big Ten Academic Alliance is a founding partner of the HathiTrust Digitial Library. Starting in 2008, the Big Ten Academic Alliance Library Directors invested in a cooperative repository that would provide researchers, faculty and students with access to an online library containing digitized versions of legacy print collections. A growing number of volumes from the Big Ten Academic Alliance library collections, approximately 111 million volumes, are held in the HathiTrust Library.
The focus of HathiTrust Library Digital Library is preserving and providing access to digitized book and journal content from the partner library collections. This includes both in copyright and public domain materials digitized by Google, the Internet Archive, and Microsoft, as well as through in-house initiatives.
Big Ten Academic Alliance library users benefit from the HathiTrust as 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.
