PA Senate Library History

History of the Library

For over two hundred years, the Library of the Senate has served as the major source of information on the Institution. Brimming with its collection of legislative documents, journals, and law books, the Senate Library is an excellent place of reference for Senate Members and staff. For those conducting research, materials may be used in the library or checked out for use in Members' offices. For visitors, the Senate Library is a reference-only library. A network of libraries in the Capitol Complex and throughout the Commonwealth may be used to satisfy requests for information not available in the Senate Library, and Senate Library staff are happy to facilitate such requests.

Beyond its role as a source of research, the Senate Library memorializes the Institutional history of the Senate through its permanent museum display and featured exhibitions, which opened in autumn 2018. These allow visitors the opportunity to learn more about the Senate's unique Institutional history, critical legislative functions, and dedicated public servants.


As part of the Senate Library's mission, a permanent museum display and featured exhibitions are on view for visitors to experience the untold story of the Pennsylvania Senate.
