Academic and research institutions worldwide. HathiTrust's partnership model is geared towards academic and research libraries with large amounts of digitized book and journal content or substantial print collections. Interested parties are invited to contact us at the email address above.
The primary requirements for partnership are the completion of a partnership agreement (view a draft agreement ) and the submission of information about library print holdings (see Print Holdings Information  for details, including what is required to receive a partnership fee estimate).
We use the print holdings information both in the calculation of fees  and in supporting lawful uses of in-copyright materials in the repository (see Accessibility  and Out of Print, Brittle or Missing ). We use Shibboleth as the mechanism of authentication for HathiTrust, and partners must be configured to login via Shibboleth  in order to receive partner services (including full-PDF download of all public domain materials, access to the HathiTrust collection builder via a local sign-on, and lawful access to in-copyright works). A partner checklist that includes these items, as well as contacts in different areas and other items, is available at http://www.hathitrust.org/partnership_checklist .
A Permissions Agreement  can be used additionally to grant access to works that are not in the public domain.
View our Partnership Checklist  for a complete list of the items and information needed for new partners.
