Account creation
You can create an account by going to HTRC Analytics and clicking “Sign Up” in the top right corner.
Anyone possessing an email address from an institution of higher education or a non-profit research organization is allowed to register, including those whose institutions are not HathiTrust members.
Many email domains from colleges and universities in the United States are recognized in our system, and you can register automatically with an email address from those institutions.
If you possess an email address that is not yet recognized by HTRC Analytics as belonging to an approved domain, you will be prompted to request an account on the sign up page. Upon review of the request, affiliates of institutions of higher education will be approved to create an account, and that email domain is then registered in our system for the benefit of others at their institution. If you are affiliated with a non-profit research institutions, such as a library, your account will also be approved, though you may be asked to provide information about your organization during the request review process. Only in certain cases are researchers from non-academic or for-profit organizations permitted to create an account.
You cannot create an account with Gmail, Hotmail, Yahoo, or similar email address.
Account deactivation
