HathiTrust Digital Library is a large-scale collaborative repository of digital content from research libraries including content digitized via the Google Books project and Internet Archive digitization initiatives, as well as content digitized locally by libraries.
HathiTrust was founded in October 2008 by the twelve universities of the Committee on Institutional Cooperation and the eleven libraries of the University of California. The partnership includes over 60 research libraries across the United States, Canada, and Europe, and is based on a shared governance structure. Costs are shared by the participating libraries and library consortia. The repository is administered by the University of Michigan. The Executive Director of HathiTrust is Mike Furlough.
In September 2011, the Authors Guild sued HathiTrust (Authors Guild, Inc. v. HathiTrust), alleging massive copyright violation. A federal court ruled against the Authors Guild in October 2012, finding that HathiTrust's use of books scanned by Google was fair use under US law. The court's opinion relied on the transformative doctrine of federal copyright law, holding that what the Trust had done to give access transformed the copyrighted works without infringing on the copyright holders' rights. That decision was largely affirmed by the Second Circuit on June 10, 2014, which found that both search and accessibility were fair use, and remanded to the lower court to reconsider whether the plaintiffs had standing to sue regarding HathiTrust's library preservation copies.
In October 2015, HathiTrust comprised over 13.7 million volumes, including 5.3 million of which were in the public domain in the United States. HathiTrust provides a number of discovery and access services, notably, full-text search across the entire repository. In 2016 over 6.17 million users located in the United States and in 236 other nations used Hathitrust in 10.92 million sessions.
As of 2019, the copyright policy states that "many works in our collection are protected by copyright law, so we cannot ordinarily publicly display large portions of those protected works unless we have permission from the copyright holder", and thus "if we cannot determine the copyright or permission status of a work, we restrict access to that work until we can establish its status. Because of differences in international copyright laws, access is also restricted for users outside the United States to works published outside the United States after and including 1879."
PageTurner is the web application on the HathiTrust website for viewing publications. From PageTurner readers can navigate through a publication, download a PDF version of it, and view pages in different ways, such as one page at a time, scrolling, flipping, or thumbnail views.
