The HathiTrust Research Center (HTRC) provides tools and access to the text of the works in the HathiTrust catalog to enable new forms of scholarly research that is driven by text mining and other computational tools that analyze a large corpus of text. Originally these functions were limited to works in the public domain, however in late September 2018 HathiTrust changed their policy and released an updated HTRC Analytics so they now provide access to the text of the complete 16.7-million-item HathiTrust corpus for non-consumptive research, such as data mining and computational analysis, including items protected by copyright. Functions included in this policy change include:
An updated chart on tool access provides additional details. More information on using the HTRC is provided in their Getting Started Guide.
