https://www.loc.gov/collections/frederick-douglass-papers/about-this-collection/

The Frederick Douglass Papers at the Library of Congress presents the papers of the nineteenth-century African American abolitionist who escaped from slavery and then risked his freedom by becoming an outspoken antislavery lecturer, writer, and publisher. The online collection, containing approximately 7,400 items (38,000 images), spans the years 1841-1964, with the bulk of the material dating from 1862 to 1865.  Many of Douglass’s earlier writings were destroyed when his house in Rochester, New York, burned in 1872.
