Athenaeum of Philadelphia

The Athenaeum of Philadelphia, located at 219 S. 6th Street between St. James Place and Locust Street in the Society Hill section of Philadelphia, Pennsylvania, is a special collections membership library and museum founded in 1814. The Athenaeum's purpose, according to its organizational principles, is to collect materials "connected with the history and antiquities of America, and the useful arts, and generally to disseminate useful knowledge" for public benefit.

The Athenaeum's collections include architecture and interior design history, particularly for the period 1800 to 1945. The institution focuses on the history of American architecture and building technology, and houses architectural archives of 180,000 drawings, over 350,000 photographs, and manuscript holdings of about 1,000 American architects.

Since 1950, the Athenaeum has sponsored the annual Athenaeum Literary Award for works of fiction and non-fiction.
