Hours and Admission

Library Hours

The Historical Society of Pennsylvania Library is open to the public Tuesday–Friday during the hours listed below. Please disregard any other hours listed outside of our website, as we have encountered incorrect information listed elsewhere before. Note that entry to the Library and paging end 45 minutes prior to close.

Tuesday: 12:30 - 5:30 p.m.
Wednesday: 12:30 - 8:30 p.m.

Administrative Hours

Our administrative offices hold regular business hours 9 a.m.–5:30 p.m. from Monday to Friday.  Although the Library is not open for public use outside of the days and hours listed above, staff do schedule business appointments and meetings during morning hours and Mondays. It is always best to pre-arrange to meet with staff, rather than stop-in and ask for them during non-public hours. HSP's main entrance on Locust street opens daily at 9:15 a.m.
