HSW_20130618_Researcher_002The  extensive collections of the Historical Society of Washington, D.C. document more than 200 years of local history and are made available to the public through the Society’s exhibits, the online catalog, and the Kiplinger Research Library on the second floor of the Carnegie Library building. Researchers are welcomed at the Kiplinger Research Library by prior appointment Tuesday through Friday.

During Spring/Summer 2017, on those same days, no appointment is required between 2 and 4pm if you are simply looking to access the ready reference resources.

Access to the library and collections is free of charge. Please note, due to the small staff and nature of special collections, appointments are required (with the exception noted above of drop-in hours for ready reference materials). Scheduling these appointments allows us to pull materials in advance, making your visit as productive as possible. To request a research appointment, please email the following information to

  • Your requested date and arrival time (the reading room is open Tuesday-Friday 10am-4pm and one Saturday per month);
  • The topic of your research inquiry;
  • Call numbers from the online catalog of materials you would like to have ready for your visit.

A representative of the Historical Society will respond to your inquiry as soon as possible.
