The Manuscript Division at the Library of Congress has custody of the papers of activist Frank Kameny (see finding aid), which contain records related to the Stonewall riots of 1969. The collection is available for use in the Manuscript Reading Room, and you are welcome to plan a research visit. Note that researchers who plan to use the Kameny papers are required to complete an agreement form upon arrival in the reading room. The Lilli Vincenz Papers (finding aid) also contain material related to the Stonewall Riots, and this collection is also available for research use, as are the Bayard Rustin Papers (finding aid), which may also be relevant to your research topic. Additional information about conducting research in the Manuscript Reading Room is available on our website, and you are welcome to contact our reference staff with any other questions you may have about this collection or about other resources available from the Manuscript Division.
A 2016 blog post from the Library of Congress on the subject of gay pride parades provides a useful list of additional resources at the end of the post. Another post about Lilli Vincenz links to two of her films of gay pride parades influenced by the Stonewall riots of 1969. For more information about these videos, please contact reference staff in the Moving Image Researc Center.
The Prints and Photographs Division has custody of a collection of posters from the Gay Rights March in New York on the anniversary of the Stonewall riots in June of 1994 (catalog record). Contact information for reference staff in the Prints and Photographs Reading Room may be found on their website.
Historical newspapers may also provide insight on the Stonewall riots, and you may also wish to reach out to the Newspaper and Current Periodical Reading Room for help locating relevant resources in this format.
