HSP has many different tools to help researchers find the materials they need within our large collection. Some tools are available on this website, but others are available only in the library at 1300 Locust Street, Philadelphia, PA 19107.
For assistance using any of our research tools, please contact our Ready Reference staff by email, call our Reference Line at (215) 732-6200 ext. 209, or just drop by the Reference Desk.
