National Archives Cartographic & Architectural

The bulk of the Record Group 26 collection of lighthouse drawings are housed in the Cartographic Branch in College Park, Maryland.  There are additional plans in the regional branches in Philadelphia, PA, and San Bruno, CA. The U.S. Lighthouse Society has scanned the plans of the main lighthouse collections that were duplicated in 42 notebooks as a finding aid for researchers. The College Park facility has additional plans from the various USCG Civil Engineering Units around the country in a collection called "U.S. Coast Guard Facilities." It includes plans created by the Lighthouse Service, Lifesaving Service, and Coast Guard.
