Get all free genealogy resources for your state, organized and ready to use — The Research Library
Most genealogists know WorldCat only as “a library search tool,” but in practice, it is one of the most important engines for discovering hidden offline and online genealogical resources. WorldCat connects thousands of libraries, archives, and historical societies into a single database, allowing you to find books, manuscripts, maps, microfilms, and digitized materials that never appear on Google, FamilySearch, or Ancestry.
This Quicksheet shows how WorldCat works and how genealogists can extract maximum value—especially when searching for rare books and local records.
