This Philadelphia Area Archival Research Portal (PAARP), formerly the PACSCL Finding Aids Site, provides access to descriptions of more than 5,000 collections from over 200 regional institutions documenting the region's vital role in our collective history, from colonization to the present day, from the everyday citizen to some of America's best known thinkers and celebrated citizens. On this site, researchers will find catalog descriptions, or "finding aids," to collections relating to local, national, and world history; the natural and social sciences; medicine; literature; religion; art and architecture; business and industry; the performing arts; and other topics.
