What The Seattle Public Library Foundation does

The Seattle Public Library Foundation is a 501(c)(3) nonprofit charitable organization founded in 1980 in Seattle, Washington, that serves as the dedicated fundraising and advocacy arm of The Seattle Public Library. It channels private philanthropy — individual donations, foundation grants, planned gifts, and endowments — into collections, programs, and capital improvements that public funding alone cannot support. The Foundation funds roughly 1 in 3 new library items and more than 50 equity-focused programs annually, and disburses over $5 million per year in grants to the library system. Since inception it has raised more than $256 million in private gifts and, through advocacy, has helped secure more than $572 million in public funding over the last 20 years, including the 1998 Libraries for All bond measure ($196.4M) and the 2019 levy renewal ($219M).

The Foundation's program portfolio spans library collections, early literacy (Global Reading Challenge, Homework Help), workforce and immigrant services (English for Work with Hopelink, English Conversation Circles), cultural programming (Authors Series, Seattle Reads, Artist in Residence), and accessibility services (Sensory Kits, the Library Equal Access Program). It runs Books Unbanned, launched in April 2023 in partnership with Brooklyn Public Library to provide free nationwide e-book access to teens and young adults counteracting book censorship, with more than 15,900 cardholders across all 50 U.S. states and 440,000+ checkouts as of April 2025. It also founded the Library Support Network (LSN), the International Public Library Fundraising Conference (IPLF), and Library Giving Day — the latter now an international movement with nearly 600 participating libraries.

Revenue comes from approximately 8,000 individual donors annually across online, phone, mail, stock, vehicle (via CARS), Donor-Advised Fund, IRA Qualified Charitable Distribution, bequest, and endowment channels, supplemented by institutional grants such as the September 2025 Carnegie Corporation of New York award ($450,000) for English language learning expansion and a historical 2006 Wallace Foundation Excellence Award ($1.5 million). The Foundation employs 101-250 staff, holds a Four-Star Charity rating from Charity Navigator and a Platinum Seal of Transparency from Candid/GuideStar, and is preparing for a 2026 Seattle Library Levy renewal.

Scale indicators12 records

Recent moves6 records

Expansion highlights5 records

Broad incumbents

• United Way of King County: Large regional community foundation that pools workplace giving and grants to local nonprofits, including library-adjacent literacy and equity programs. Comparable as a broader community philanthropic vehicle operating in the same Seattle geography.

Direct peers

• San Francisco Public Library Foundation: Nonprofit foundation dedicated to raising private support for the San Francisco Public Library. Direct peer as a West Coast library foundation with similar funding priorities around equity, literacy, and programming above public funding levels.
• Library Foundation of Los Angeles: Private foundation that funds programs and collections for the Los Angeles Public Library. Directly comparable to the Seattle Public Library Foundation in mission, donor structure, and grantmaking to a major metropolitan library system.
• New York Public Library Foundation: The private 501(c)(3) fundraising arm for the New York Public Library, one of the largest library foundations in the U.S. Directly comparable as a private foundation raising endowment and annual gifts to supplement public library funding for collections, programs, and special initiatives.
• Boston Public Library Fund: Philanthropic foundation supporting the Boston Public Library with annual and capital campaigns. Direct peer as a city-based library fundraising foundation operating with comparable revenue model and program priorities.
• Brooklyn Public Library Foundation: Fundraising arm of Brooklyn Public Library and the originator of the Books Unbanned initiative that SPL joined. Direct peer and partner on shared national anti-censorship programming, making it a natural benchmark for cross-library philanthropic collaboration.
• Chicago Public Library Foundation: Independent nonprofit foundation supporting the Chicago Public Library system with annual giving, endowment, and program funding. Directly comparable as a city-level library foundation with a similar philanthropic model serving a major U.S. public library system.

Regional players

• San Diego Public Library Foundation: Foundation supporting the San Diego Public Library, which has also joined the Books Unbanned coalition. Comparable as a regional library foundation in a different metro market, useful for benchmarking fundraising productivity outside the Pacific Northwest.

Others

• Carnegie Corporation of New York: Major U.S. grantmaking foundation that awarded SPL Foundation a $450K grant in 2025 for English-language learning. Relevant as an institutional donor and peer in the broader foundation ecosystem, though its mission and scale are far larger.

Emerging players

• Friends of the Seattle Public Library: Distinct nonprofit that advocates for the library and raises funds through FriendShop book sales. Comparable as a sibling fundraising organization supporting the same library system via a different revenue model (volunteer-driven retail rather than major-gift philanthropy).
