From the site:
The Theodore Roosevelt Collection, housed in Harvard's Houghton and Widener libraries, is a major resource for study of the life and times of the twenty-sixth president of the United States.
The collection originated as a research library opened in New York City by the Roosevelt Memorial Association in 1923. It was presented by that organization (known since 1956 as the Theodore Roosevelt Association) to Harvard University in 1943.
