How to Find the Materials You Need
Founded in 1824, the Historical Society of Pennsylvania is one of the oldest historical societies in the United States. Our collection includes some 600,000 printed items and more than 21 million manuscript and graphic items, including the holdings of the Balch Institute for Ethnic Studies (which merged into HSP in 2002) and the Genealogical Society of Pennsylvania (through a 2006 Strategic Alliance Agreement).
HSP provides a variety of tools to help researchers find the materials they need within this large collection. Some tools are available online, but others are available only in the library at 1300 Locust Street, Philadelphia, PA.
For assistance using any of these 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.
Discover - Online Catalog
For most users, Discover is the best place to begin a search. This online catalog includes information about HSP’s print materials, manuscript collections, maps, microfilm, and more. Please note that each record in the online catalog includes a “holdings” tab and a “description” tab; you may find helpful information on each tab. While the majority of HSP’s holdings are captured in this catalog, it includes only collection-level descriptions for manuscript items. Note that some microfilm from the Balch Institute for Ethnic Studies, which merged with HSP in 2002, is not currently available in Discover. For more on those holdings, see the guide at the Reference Desk.
HSP’s Digital Library is a growing online repository of images and digital files from our collections. To date, the Digital Library includes more than 75,000 images of manuscripts, maps, photographs, and prints, as well as video and audio records. Several of HSP’s most notable collections, including the David J. Kennedy watercolors, are digitized in their entirety. All images are available for purchase as both archival prints and digital downloads, and new content is added every week.
Patron Access Link (PAL)
HSP provides access to a variety of online resources through PAL, or the Patron Access Link. PAL provides links to all HSP online catalogs, as well as access to the HSP Encounters genealogy databases and all subscription-based sites available in our Reading Room, including Ancestry.com Institution Edition, JSTOR, and more. The PAL menu includes detailed information about which resources offer HSP members remote access and which are available in the library.
Some manuscript collections have finding aids that provide background information, description about how the collection is organized, and inventories of what is contained within the collection. Some finding aids are available online, either as PDFs or as searchable web text. Other finding aids are available only at HSP’s Reference Desk for now.
You can find collection-level descriptions of our manuscript collections in our online catalog Discover; when viewing the collection record, make sure you click on the “Description” tab to see that text. Sometimes, you’ll find a link to a finding aid in the collection record in Discover. If you don’t see a link, also check out our list of finding aids and the Balch Manuscript Guide, which provides links to other online finding aids. Please note that we add new finding aids regularly. If you still have questions, ask a Reference Librarian.
HSP’s collections center on eastern Pennsylvania, southern New Jersey, and parts of Delaware and Maryland, but also include a wealth of materials on the eastern United States, the founding of this country, and the diversity of ethnic and immigrant experiences across the United States. HSP has created an assortment of subject guides that highlight areas of particular strength in our collections.
Balch Manuscript Guide
This online guide contains short descriptions of the collections (manuscripts, photographs, serials, microfilm) of the Balch Institute for Ethnic Studies, which merged with HSP in 2002. The Discover online catalog also includes collection-level descriptions for Balch materials, but this guide is organized by ethnic group. Note that this guide is no longer actively maintained.
HSP maintains a series of card files in the Reference Room. Information in these files may not be captured by online-only catalog searches. Card files in the Reference Room are broken down into separate sections for manuscripts, broadsides, graphics, maps, sheet music, Afro-Americana, genealogical resources, and newspapers. The manuscripts catalog (PC1) provides item-level access to several large manuscript collections.
Researchers can also browse these cards via FamilySearch.org. Note that these digital images do not yet have metadata attached (that will be coming in the future). For now, users can flip through the card images as if browsing through the physical cards on-site. Browse the cards using HSP's Patron Access Link.
PC 1 - Manuscript catalog
This catalog indexes at the item level nearly 1 million manuscript resources that were processed between the late 19th century and the 1970s, including letters, diaries, accounts, and minutes. Beginning in the 1970s, HSP switched to collection-level processing, and collection-level cards were added to PC1 into the 2000s. PC1 is primarily a name index and is no longer actively maintained, but it remains an extraordinary resource for deep access to manuscript collections.
