The Smithsonian Libraries Research Annex (SLRA) holds over 50,000 monographs, over 300,000 periodical holdings, and is the most subject-diverse branch within the Smithsonian Libraries system. SLRA’s collection of late 19th and early-mid 20th Century trade periodical literature is a scarce collection that includes U.S. Patent Office Library legacy serials. These trade periodicals document the material culture of the Industrial Era in the United States and Great Britain, giving nuance to the literal machinations of Victorian and turn-of-the century middle class life. All aspects of American life, as well as major developments in industry like the steam engine, electricity, and the mechanical printing press are represented.

Parlett L. Moore Library is a member of the Library Information Management System (LIMS) of the University System of Maryland and Affiliated Institutions (USMAI). This collaborative effort permits state higher education institutions to share resources. LIMS provides a USMAI union online public access catalog that contains more than 1,400,000 titles

The Museum Support Center Library serves the research needs of all staff at the Smithsonian’s Museum Support Center (MSC) in Suitland, Maryland.

The Smithsonian Environmental Research Center Library was founded in 1977 at the Chesapeake Bay Center for Environmental Studies (CBCES) to support the Center’s research and education programs. The CBCES was renamed the Smithsonian Environmental Research Center (SERC) in 1986 upon the closing of the Smithsonian Radiation Biology Laboratory (SRBL) in Rockville, MD and the partial merging of staff and collections.

In operation since 1999, the Vine Deloria, Jr. Library of the National Museum of the American Indian (NMAI) is the 20th library of the Smithsonian Libraries and is located in Suitland, MD in the Cultural Resources Center (CRC) where it shares research and collection space with the NMAI Archives.
The Deloria Library research materials include over 40,000 volumes of books, periodicals, microfilm, and media in the main collection; a small, but growing rare book section; Native American Artist Files; and, ephemera. The Library collections cover the broad range of topics and disciplines related to the histories, cultures, arts, and contemporary issues of Native American and Indigenous peoples in the Western Hemisphere. Strengths in the collection are tribal histories, biographies, traditional and modern art, language and literature – including children and young adult materials, Native knowledge, and collections care. Because Native Studies is interdisciplinary by nature, there is overlap of coverage in other Smithsonian libraries, so research could include materials from other libraries.
