According to the American Library Association, these are the largest libraries in the United States. This list includes private research libraries at major universities, and also includes branch locations and restricted access collections.

Of the libraries on the list, the library at Harvard is the oldest; the university and its library were founded in 1638. But, The Boston Public library is the second ever modern public library in the world. It is the first major library funded by local taxes (preceded only by the little Peterborough town library in neighboring New Hampshire). The project was pushed through to completion after rumors surfaced of a similar project in New York ignited an intercity competition.
