Theodore Roosevelt Collection at Harvard University

- Essentially the Theodore Roosevelt Library, this uniquely comprehensive group of publications, pictures, ephemera, and other archival materials relating to Theodore Roosevelt was first assembled by the Theodore Roosevelt Association and opened as the Roosevelt Memorial Library in 1923.

Two decades later the collection was donated by the Association to Harvard University, TR's alma mater, where it was established as a special unit of the Harvard College Library, the center of Harvard's complex library system. See link for hours and contact information.
