Smithsonian Libraries and Archives (SLA)

What Smithsonian Libraries and Archives (SLA) does

Smithsonian Libraries and Archives (SLA) is the library and archival unit of the Smithsonian Institution, a federal trust instrumentality of the United States established by Congress in 1846. Formed in December 2020 through the merger of Smithsonian Libraries and Smithsonian Institution Archives, SLA operates 21 specialized research libraries plus the institutional archives across Washington DC, Maryland, Virginia, New York City, and the Republic of Panama. The organization maintains nearly 3 million library volumes, over 44,000 cubic feet of archival materials organized into 5,096 collections, and more than 35,000 digitized books and manuscripts. Its primary users are Smithsonian staff and affiliated researchers, visiting scholars, students from K-12 through graduate level, and the general public, with services delivered through physical reading rooms, exhibitions, and an extensive digital footprint.

SLA's core product surface combines physical and digital infrastructure. The OneSearch discovery platform unifies search across the library catalog, e-journals, articles, books, and research databases (JSTOR, Project MUSE, Web of Science, ProQuest Historical Newspapers, Ancestry Library Edition). The SIRIS library catalog indexes combined collections across all branches, while the open-source Macaw tool (Apache v.2 licensed) automates page-level metadata for scanned books and packages submissions to Internet Archive. The Electronic Records Program, established in 2004, manages preservation of the Institution's born-digital history, supported by the DArcMail internal workflow application. SLA is a founding member and administrative Secretariat host of the Biodiversity Heritage Library (BHL) consortium, in operation since 2006. Specialized physical holdings include the Dibner Library of the History of Science and Technology (approximately 35,000 rare books and 2,000 manuscript groups) and the Joseph F. Cullman 3rd Library of Natural History. The exhibitions and education program produces curated physical and online shows (Imagining Bison, Nature of the Book, Music HerStory).

SLA does not operate a commercial revenue model. Primary funding flows from congressional appropriations channeled through the Smithsonian Institution, supplemented by tax-deductible donations (online gifts, planned giving/bequests, charitable gift annuities, endowments at $50,000+, and Adopt-a-Book), grants from foundations such as the Gladys Krieble Delmas Foundation and the Arhoolie Foundation, and partnership support. Core services to researchers and the public are free; fees apply only for reproduction/photocopying, interlibrary loan to external users, and specialized research services. SLA's customer base is structurally internal-concentrated, with the Smithsonian Institution serving as both anchor funder and primary user organization; visiting researchers, students, and the general public constitute secondary, non-paying audiences reached through exhibitions, programs, and digital channels.

Expansion highlights5 records

Broad incumbents

• Library of Congress: The U.S. national library and a federal research institution comparable to SLA in scale, scope, and special-collections mandate. Both occupy government-backed, multi-format library/archives roles serving both internal researchers and the public.
• British Library: UK national library operating at comparable scale as a national research library with rare collections, digital preservation programs, and exhibitions. Peer in scope of mission rather than direct geographic competition.
• Harvard Library / Harvard Museums of Science & Culture: Operates a network of 70+ libraries with substantial rare books, manuscripts, and university archives. Comparable to SLA in operating specialized libraries embedded within a broader research/museum ecosystem.

Emerging players

• HathiTrust: Large-scale collaborative digital preservation repository and access platform for academic and research libraries. Comparable to SLA's digital preservation and OneSearch discovery mandate at the consortia level.
• Digital Public Library of America (DPLA): National digital platform aggregating digital content from libraries, archives, and museums — including SLA's content via BHL. Comparable as a digital discovery infrastructure for cultural-heritage collections.

Direct peers

• Getty Research Institute: Research library and archive specializing in art history, visual culture, and special collections. Comparable to SLA's branch libraries supporting art, design, and cultural-heritage research missions.
• New York Public Library: Major research library holding rare books, manuscripts, and special collections across multiple research branches. Comparable to SLA in operating a multi-branch research library system with public-facing exhibitions and educational programming.
• Internet Archive: Non-profit digital library hosting digitized books, manuscripts, and audiovisual materials. SLA uses Internet Archive as a hosting and preservation partner via Macaw, making them operational peers in cultural-content digitization and preservation.
• National Archives and Records Administration (NARA): U.S. federal agency responsible for preserving and providing access to historical government records. Directly comparable to SLA's institutional archives function across preservation, reference, digitization, and public access.
• Biodiversity Heritage Library (Consortium): Consortium of natural history and botanical libraries that SLA co-founded and historically administered. Operates at the same intersection of digitized special collections, biodiversity literature, and open-access discovery.
