HTRC Analytics is the gateway to most HTRC tools and services. It is a set of complementary tools for studying sub-collections of volumes from the HathiTrust Digital Library (called worksets) using computational text analysis. On the Analytics website, you can create worksets for textual analysis, run text analysis algorithms, set-up and run a Data Capsule secure analysis environment, and more.

The basics

HTRC Worksets

Worksets are sub-collections of HathiTrust volumes created by researchers. You can run HTRC algorithms against worksets in order to analyze them or download their Extracted Features. Worksets can be cited, and researchers can choose to make their worksets public or private.

HTRC Algorithms

Web-based, click-and-run tools that perform computational text analysis on worksets, which are user-created collections of volumes. No programming required.

HTRC Data Capsules

Secure virtual environments for non-consumptive text analysis, where researchers can implement their own data analysis and visualization tools.

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

Accounts that have not been active for more than one year are deactivated. HTRC checks activity monthly to identify inactive accounts. Once an account has been deactivated, a researcher will experience an error if they attempt to log into their account. A deactivated account can be reactivated by contacting HTRC at
