The Estelle and Melvin Gelman Library, simply referred to as the Gelman Library, is the main library of The George Washington University, and is located on its Foggy Bottom campus. The Gelman Library, the Eckles Library on the Mount Vernon campus and the Virginia Science and Technology Campus Library in Ashburn comprise the trio known as the George Washington University Libraries. The Himmelfarb Health Sciences Library and the Jacob Burns Law Library also serve the university. The Gelman Library is a member of the Washington Research Library Consortium and the Association of Research Libraries.
The seven-story library building contains over two million volumes. Gelman Library is constructed in the Brutalist architectural style of the 1970s. It features a concrete façade punctuated by windows that are divided by projecting vertical slabs. For most of the year, parts of the library are open 24 hours day, seven days per week for use by students, faculty and staff. The library's seventh floor is home to the National Security Archive, a research institution that publishes declassified U.S. government files concerning selected topics of American foreign policy. It was a National Security Archive Freedom of Information Act request that eventually made the Central Intelligence Agency's so-called "Family Jewels" public.
