Jane C. Sween Research Library and Special Collections



At this time the library remains closed, consistent with county restrictions, Montgomery County Public Libraries, and other regional research facilities. No date has been set for reopening.

In the meantime, we are still able to process remote research requests. Please contact the Librarian/Archivist or visit our remote research page for more information.




The Jane C. Sween Research Library and Special Collections is located at the Beall-Dawson Historical Park in Rockville. Named in honor of its first librarian–researcher, current volunteer, and author Jane C. Sween–the library strives to collect, preserve, and make available the rich history of Montgomery County and its residents in the form of primary and secondary resources related to local history and genealogy.
