Harvard has about a hundred specialized libraries. Each library has a distinct personality and many have changing displays that showcase especially beautiful or historically intriguing items from the collections. The libraries most visited by OEB students for research purposes are the Botany Libraries, the MCZ Library, the Biolabs Library, Cabot Science Library, and Countway Library of Medicine. If there is an item you need that is not available at a Harvard library near you, an interlibrary loan can make your life easier.
