Becoming A Member
Who is eligible?
Academic and research institutions worldwide. HathiTrust's membership 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.
What are the requirements of membership?
The primary requirements for membership are the completion of a membership 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 membership 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 members must be configured to login via Shibboleth in order to receive members 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 member 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 Creative Commons Declaration Form can be used additionally to grant access to works that are not in the public domain.
