Contains documents representing a broad spectrum of militant political, social and religious dissent in the United States, from the post-World War II period to the present. The Collection currently exceeding 168,000 items emanating from over 5,000 organizations, constitutes the country's largest research collection of right and left wing U.S. extremist groups, from 1950 to 1999.

The collection began when Gordon Hall, a young veteran of the Pacific Theatre during the war, first encountered the printed propaganda issued by domestic hate-your-neighbor organizations/groups in the late 1940's. He supported his investigations and research of these organizations by giving public lectures about them. Materials from all corners of the country were collected, enabling him to document statements made in lectures as well as in a growing number of expository articles written for newspapers and magazines.

Grace Hoag, an alumna of Smith College, began collaboration with Hall during the 1960's, assisting the research and investigation and expanding the collection beyond its initial emphasis.
