Customer segments include individual members (the primary base), researchers and scholars using the architectural archives, cultural program attendees, and architecture and preservation professionals applying for Peterson Fellowships.

The Athenaeum is governed by a Board elected by Shareholders and led by Executive Director Beth Shalom Hessel, with a staff of approximately 20 across executive, curatorial, librarian, archivist, imaging, and administrative functions. Membership reached 2,986 at the end of FY2025 (a 12.5% year-over-year increase) and total FY2025 income was $2,102,135, with programmatic expenses of $1,833,851.

Direct peers

• Library Company of Philadelphia: Founded in 1731, the Library Company of Philadelphia is a fellow subscription/membership-supported research library in the same city with overlapping 18th–19th century American history and architecture holdings. It is the closest geographic and functional peer, sharing members, scholars, and Philadelphia's preservation community.
• Redwood Library and Athenaeum: America's oldest lending library (1747), operating as a private membership institution with circulating collections, art, and architectural programming in a National Historic Landmark building. Closely aligned with the Athenaeum of Philadelphia on heritage-building operations and member-supported model.
• Providence Athenaeum: Another private membership-supported library (1836) offering circulating collections, lectures, and exhibitions. Smaller scale but identical member-supported library economics and mission, making it a tight comparator for engagement, programming, and membership model benchmarking.
• Historical Society of Pennsylvania: Located in Philadelphia, HSP operates a research library and archives focused on Pennsylvania and American history with similar researcher/scholar segments. Direct overlap on Philadelphia regional history collections and preservation community membership.
• Boston Athenaeum: A private membership library founded in 1807 with a circulating collection, special collections, exhibitions, and cultural programming — a near-mirror operating model. Comparable scale, similar reliance on member dues and endowment, and overlapping mission to serve intellectually curious members in an iconic historic building.
• The Grolier Club: A private membership club and library in New York devoted to the art of the book, with exhibitions, lectures, and a research library. Comparable membership-based cultural organization with similar programming, audience, and operating economics.
• New York Society Library: Founded in 1754, New York's oldest library is a private membership library with circulating collections, cultural programming, and a historic building. Highly comparable operating model and customer base (intellectually engaged urban professionals).
• American Philosophical Society: Philadelphia-based learned society with a research library, museum, and publications focused on scholarly inquiry since 1743. Shares the same member/scholar audience, historic-building operations, and Philadelphia cultural ecosystem.
• St. Louis Mercantile Library: America's oldest lending library west of the Mississippi (1846), operating as a private membership library at the University of Missouri-St. Louis with special collections and cultural programming. Closely analogous operating model and member-supported structure.

Broad incumbents

• Folger Shakespeare Library: A larger, well-endowed research library in Washington, D.C. with world-class special collections, exhibitions, and programming. Not a direct membership-circulating library, but highly relevant as a comparator for endowment scale, scholarly programming, and digital collection strategy in the heritage research-library space.
