Overview
Mission
The Athenaeum of Philadelphia is a member-supported circulating library, research archive, and cultural forum dedicated to harnessing our resources — our expert staff, our collections of books, art and architecture treasures, and our National Historic Landmark Building — to strengthen our growing urban community through cultural engagement and fellowship.
What it reported doing in 2024
Museum/library building: the athenaeum's three largest program services, as measured by expenses in fye 2025 were 1) maintaining and operating the athenaeum's 1847 national historic landmark building and its circulating and special collections; 2) paying the salaries and benefits of the staff needed to provide programs and services to members and the public and care for the building and collections; and 3) provide public research support. 1) the athenaeum building and collections connected with the history and antiquities of america, and the useful arts, disseminate useful knowledge for public benefit requires care and upkeep. The special collections consist of more than 800,000 books, manuscripts, maps, photographs, and architectural drawings of particular value to architectural historians, historians, and preservationist. Thousands are available for research on two sites maintained by the athenaeum: philageohistory.org and philadelphiabuildings.org and were accessed by more than 150,000 people in fye 2025, while staff served more than 30 research requests in person, phone, or via email each month. The athenaeum's circulating collection of books, ebooks, audiobooks, and periodicals that are part of the circulating building are not capitalized. 2) personnel costs make up a large percentage of the annual budget. Our team of librarians and curator care for our collections and make them available to members and researchers. In fye 2025, more than 18,000 items circulated. Front desk, membership, and programming staff provided hospitality, tours, and a robust schedule of more than 170 programs and events in fye 2025, almost all of which were open to both members and the public. 3) public research support. The athenaeum supports a robust program of fellowships, internships, and prizes through the charles e. Peterson fellowship and the peterson prizes. Each year, the charles e. Peterson fellowship committee reviews applications and awards funding to researchers and scholars whose projects focus on american architecture, design, landscape, or engineering prior to 1860. The fellowship also supports 1-3 undergraduate or graduate interns to gain experience working with our architectural collections. The charles e. Peterson prizes are jointly overseen by the athenaeum of philadelphia, the library of congress, the national park service, and the american institute of architects, and award cash prizes to teams of college students for the best architectural drawings of historic structures in conjunction with the national park service's historic american buildings survey (habs) program.
Operating model
- Revenue model
- Mixed. Its operating money came from several sources; no one source provided a clear majority.
- Distribution model
- Direct operator. The filing allocates 96% of reported program-service expenses outside its grant, affiliate-payment, and member-benefit lines. This expense classification does not rule out separately announced grant awards.
The verdict
SUPPORTED - A large share of available resources goes toward mission work and the filed numbers largely add up. Fundraising costs are high for each dollar raised and reported officer compensation is a large share of total spending, which may reflect staffing concentration.
