More Than 70 Different Libraries...

Harvard's library system includes many individual libraries: some are here in Massachusetts, others as far away as Italy. Some have circulating collections, with materials available to borrow; some have rare books, manuscripts, and archival materials that you can consult in a reading room on-site. Some collect materials on a specific topic, such as Botany, or the History of Women in America, and some collect materials across a very broad set of topics, such as the Social Sciences and Humanities.

Use to explore Harvard's many different libraries: you can explore library by library or browse through featured collections. Select the library's name to access detailed information about a particular library's area of focus and guidance for researchers (usually under "Full Website").

A great way to explore our libraries in person is to visit a library exhibition.
