HathiTrust Research Center (HTRC) elephant head logo

The HathiTrust Research Center (HTRC) is the research arm of HathiTrust.  It facilitates scholarly research

using the large-scale HathiTrust Digital Library by providing mechanisms for researchers to access content in the HathiTrust and study it using computational tools for text analysis.

Entire Collection Piloted for TDM

The HathiTrust Research Center has expanded its services to support computational research on the entire collection of one of the world’s largest digital libraries, held by HathiTrust. HathiTrust’s collections include over 14 million digitized volumes, including more than 7 million books, 725,000 US federal government documents, and 350,000 serial publications. Previously the HathiTrust Research Center supported analysis of only the public domain subset of the HathiTrust collection. Researchers will now be able to explore the entire collection and run an algorithm against all 14 million volumes. The change is being piloted in 2016 and is expected to be more widely available in 2017.
