HathiTrust is one of the most powerful and overlooked genealogy tools on the internet. Containing millions of digitized books, journals, government documents, local histories, city directories, school reports, and genealogical society publications, it rivals — and frequently exceeds — Google Books in usefulness for family history research.

What makes HathiTrust exceptional is its focus on:

  • academic-quality digitization
  • rare local publications from small towns, counties, and organizations
  • searchable text within the full item, allowing deep discovery
  • government publications not available elsewhere
  • genealogical society journals and newsletters

This is not a site where you find an ancestor’s profile handed to you. It is a site where you find rich contextual information, and sometimes direct references to ancestors in surprising sources. This Quicksheet shows you how to navigate the site, what to search for, and where genealogists often find “hidden gems” that don’t appear in traditional records.
