Admission to the library is included with suggested museum admission. For upcoming closures, directions, and suggested admission rates, see the Visit page. To learn more about the history of the Othmer Library, see About the library.

Archival Research

An appointment is necessary to use archival materials, as these collections are not stored in our reading room. Please submit requests for appointments at least two days before the date you would like to visit. Email [email protected] to request an appointment; you will receive an email confirmation once you are scheduled.

Several collections are stored offsite and require three weeks notice to use:

BHS is currently working on Portal to the Past: Creating Brooklyn Historical Society’s Digital Map Collection, a project that will increase public access to the institution’s extensive collection of maps through conservation, digitization, and the creation of a web-based portal. At the completion of the project, we expect more than 1,600 maps to be digitized and published online, similar to our award-winning Oral History Portal. As we prepare the maps over the next months, there will be limited access to maps in the reading room. Please email [email protected] at least two days in advance of your visit to check on map availability. For information and updates on this exciting project, subscribe to the BHS blog by signing up for our e-newsletter.

Other materials are available for use during library open hours and do not require an appointment. These include books, some maps, atlases (including fire insurance atlases), directories, periodicals, and land conveyance records, as well as databases, including our image and oral history databases, Brooklyn Daily Eagle and Long Island Star newspapers, and
