Celebrating 125 Years

Our mission is to provide leadership and support in promoting genealogy through education, preservation, and access to Pennsylvania-related genealogical information.

Founded in 1892 as a non-profit organization, the Genealogical Society of Pennsylvania (GSP) was among the first in the United States to recognize the value of collecting and preserving the records of the ancestors whose lives now comprise our American History. GSP is committed to preserving and publishing primary source records and to helping people to find their Pennsylvania ancestors. Continuing dedication to this service enables the Society to make an ongoing contribution to the cultural life of our city, state, and country.


Online GSP collections are on the Public Collections and Member Collections pages. The GSP Library Catalog includes books held by the library of The Genealogical Society of Pennsylvania. We also have several manuscript collections and other collections that are not yet listed online. We are currently creating a full inventory of the collections.
