Looking to start your own genealogical research and don’t know what resources are available to you? You’re in the right place!  

Use this guide for finding vital records, exploring online genealogy databases, and as a compass pointing to other avenues of research as you explore your family’s history. Many of the resources outlined here contain records specific to the Western Pennsylvania region, but you will find others, like Ancestry and FamilySearch, that can help you to expand your search.    

If you are looking for birth, death, marriage or naturalization records, this guide will help to explain which records are held by the Library, which are accessible through the Library’s online resources, and which records might have to be accessed elsewhere, through a government agency, for example. 

Explore the genealogy databases offered through the Carnegie Library of Pittsburgh. 

Finally, if you need the assistance of a librarian, fill out one of  Research Request Forms to have a library staff member assist you with a research question.  Please note that all requests are answered in the order in which they have been received and may take 4-8 weeks to be completed.
