The Library’s Pennsylvania Department at CLP – Main (Oakland) is the place to come to research your family tree or delve into the history of Pittsburgh, Allegheny County and the rest of the Keystone State. The Department’s extensive resources on genealogy and Pittsburgh and Pennsylvania history include historic clipping files and the Pittsburgh Photographic Library. This collection of more than 100,000 negatives and prints provides a visual history of our city from its origin through its industrial development and renaissance. As subject specialists, the Pennsylvania Department staff is always available to answer questions, provide research guidance and recommend and assist in finding materials.
In order to improve our research request system, the Pennsylvania Department will temporarily suspend its research program starting on November 17. Any requests currently in the research queue will be completed. Please check this page for updates regarding our new system.
During this brief time, we encourage patrons to consult FamilySearch.org, which has digitized copies of many vital records. This video has instructions to help you find Allegheny County records if you’re not familiar with the site.
We appreciate your patience while we streamline our process.
