Detre Library & Archives

The health and safety of our visitors, volunteers, and staff remains our top priority. In compliance with the recommendations of local and state officials to help prevent the spread of COVID-19, the Heinz History Center, Western Pennsylvania Sports Museum, Fort Pitt Museum, and Detre Library & Archives will remain temporarily closed to the public until further notice.  

All public programs originally scheduled through April 30 are either postponed or canceled. This is a fluid situation, so please continue to follow our website and social media platforms for the most up-to-date information on our museums and programs.

The Thomas & Katherine Detre Library & Archives at the Senator John Heinz History Center is Western Pennsylvania’s preeminent source for researching the region’s rich history.


Access to the Detre Library & Archives at the Senator John Heinz History Center is free for all visitors. Visitors coming to the History Center solely to use the Library & Archives will not be charged admission; they will be given a special Library & Archives sticker at the Admissions Desk and directed to the 6th floor, where they will sign in. Paid admission to the museum is required to see the exhibits.
