Archive and Research Room of the Pennsylvania State Historic Preservation Office

The Pennsylvania State Historic Office (PA SHPO) and PHMC have been collecting information concerning historic places and archaeological sites for the greater part of a century.  PA SHPO's collection includes:

    • Historic resource files
    • Archaeological resource/ Pennsylvania Archaeological Site Survey (PASS) files
    • Archaeological and historic resource survey reports.

From 2017 to 2019, PA SHPO digitized the historic and archaeological resource records and reports held in the PA SHPO's Archive and Research Room. This information is now available online via the Pennsylvania Historic and Archaeological Resource Exchange (PA-SHARE).  

PA-SHARE includes a map-based inventory of the historic resources, archaeological sites, surveys, historical markers, and program-related information stored in the files of the Pennsylvania State Historic Preservation Office (PA SHPO).

PA-SHARE is the PA SHPO's chief storehouse of information and includes an ever-expanding number of digital records.  Users with Pro and Business subscription accounts can view all of PA SHPO's scanned Archive and Research Room files online through PA-SHARE. Guest and Basic account users can see only limited information via PA-SHARE.

Researchers interested in accessing PA-SHARE resource records without purchasing a subscription or reviewing project files can visit the PA SHPO's main office in Harrisburg.  Researchers will be able to use a dedicated PA-SHARE research station and, if needed, request paper files from the PA SHPO's Archive and Research Room. 


Beginning, September 1, 2021, the Archive and Research Station will be open to the public by appointment only on Mondays, Wednesdays, and Fridays from 9:00 AM to 12:00 PM and 1:00 PM to 4:00 PM.

Please note that 3:00 PM is the latest time appointments will be scheduled for the day. The PA SHPO Archive and Research Station will be closed on all state holidays and may also be closed during different periods throughout the year.

This schedule is subject to change.
