List of the largest libraries in the United States
The largest public library in the United States—and the largest library in the world—is the Library of Congress in Washington, D.C., which is the "de facto" national library of the United States. It holds more than 167 million items, including "more than 39 million books and other printed materials, 3.6 million recordings, 14.8 million photographs, 5.5 million maps, 8.1 million pieces of sheet music and 72 million manuscripts."

Vassar College
Vassar is home to one of the largest undergraduate library collections in the U.S. The library collection today – which actually encompasses eight libraries at Vassar – contains about 1 million volumes and 7,500 serial, periodical and newspaper titles, as well as an extensive collection of microfilm and microfiche, with special collections of Ellen Swallow Richards, Albert Einstein, Mary McCarthy, and Elizabeth Bishop. Vassar has been a Federal Depository library for selected U.S. Government documents since 1943 and currently receives approximately 25% of the titles available through the Federal Depository Program. Since 1988, Vassar has been a New York State Reference Center, part of the New York Depository Program. The library also selectively purchases United Nations documents.
