HathiTrust Membership & Infrastructure

HathiTrust Membership & Repository Size

The HathiTrust Digital Library and partnership has grown rapidly. Between 2008 and 2016, HathiTrust Digital Library grew to hold more than 15 million digital volumes and there are more than 120 partner libraries from the United States and around the world.

Everyone may read full view volumes on HathiTrust. For users in the United States, roughly 38% of the HathiTrust corpus is full view and available for reading. Due to differing copyright laws and restrictions outside of the United States, international users may access roughly 24% of the volumes for reading. The remaining volumes are restricted view due to copyright law or privacy considerations, but are available to everyone worldwide for full-text search.

HathiTrust Governance

HathiTrust is co-owned and co-managed by the partner libraries. It is governed by a Board of Governors who are appointed or elected from partner libraries, and the Executive Director. Mike Furlough became Executive Director of HathiTrust in 2014, following the founding Executive Director, John Wilkin.
