HathiTrust Data API

The HathiTrust Data API can be used to retrive content (page images, OCR, and in some cases whole volume packages), as well as metadata for HathiTrust volumes. There are two methods of accessing the Data API: via a Web client, requiring authentication (users who are not members of a HathiTrust partner institution must sign up for a University of Michigan "Friend" Account), and programmatically using an access key that can be obtained at http://babel.hathitrust.org/cgi/kgs/request. Complete documentation of the API is available below. Version 2 is the most recent version.
