If you hit a dead end in your genealogy research at the Historical Society of Pennsylvania, try your luck at one of over 100 small archival repositories and historical societies in the Philadelphia area!

HSP's Hidden Collections Initiative for Pennsylvania Small Archival Repositories (HCI-PSAR) has been dedicated to uncovering the important archival resources in the Philadelphia area since September 2011. In that time we have found some very useful genealogical collections! From Civil War veterans' club records to local tax rolls to orphanage registers, many important resources can be found at small archival repositories.

Our project had a broad-based survey approach, so we have not had the opportunity to index those collections for names, nor have we digitized anything. However, we have cataloged the collections with general information about the types and quantity of information you can expect to find. Go to http://dla.library.upenn.edu/dla/pacscl/ancillary.html?id=collections/pacscl/repositories2 to browse the collections we have cataloged so far, and keep an eye on the site because we'll be adding to it until Fall 2014.

The archival resources most useful to genealogists fall into three broad categories: primary source records, genealogy research papers, and family files. Just about every small repository we surveyed had something for each category, so take the list below as a very selective subset of some exceptional examples.

Primary Source Records, especially membership registers, contain valuable genealogical data.

• Records of various Grand Army of the Republic posts, Grand Army of the Republic Museum and Library
• Pennsylvania Society for New England Women records, Strawberry Mansion
• Wilson D. Puhl tax collection records, Lower Pottsgrove Historical Society
• Foulke and Long Institute for Orphan Girls records, Germantown Historical Society
• Lansdale (Pa.) tax assessments, Lansdale Historical Society

Genealogy Research Papers, collected by individuals or family associations and then later donated to archival repositories, often reach to the far fringes of the family tree. You are in luck if a branch of your family overlaps!

• Dr. John H. Kressman genealogy research files, Historical Society of Trappe, Collegeville, Perkiomen Valley
• Holly K. Green genealogy files, slides and notes, Goschenhoppen Historians
• Harry E. Reiff genealogy research files, Historical Society of Montgomery County
• Yost Family Association records and Bergey Family Association records, Historical Society of Montgomery County
• Conrad Wilson and William E. Frame genealogy research files on the Bartram family, Bartram's Garden

Family Files are alphabetical files on local individuals or families maintained by archival repositories, usually full of materials donated by prior researchers. They often include copies of newspaper clippings, obituaries, family trees, and narrative family histories. Sometimes there are also primary source documents (such as loose receipts or a few photographs) in the family files.

• Historical Society of Montgomery County family files
• Germantown Historical Society family files
• Limerick Township Historical Society genealogy research collection
• American Swedish Historical Society genealogy collection
• Conshohocken Historical Society family vertical files

Hopefully the resources listed above have given you some ideas for how to continue your genealogical research beyond HSP. Don't forget about the small archival repositories!
