150 Historic Maps Added to Dig DC


DC Public Library Special Collections is proud to announce the release of 150 more historic Washington, DC maps in Dig DC, the online portal to DCPL Special Collections. These maps cover the District of Columbia and the region from the turn of the century to the 1970s. To see them, head on over to the Maps: City & Regional collection in Dig DC!

Some highlights of the rare maps recently added to this collection include: 

The dates covered in the online map collection now range from 1768 through 1972. DCPL Special Collections has already digitized nearly 275 historic maps from the Washingtoniana Map Collection and is currently working to digitize more. Check back in early 2017 for the next release, which will include maps from the 1970s to the 2000s, as well as a just-discovered 1856 plat book!

While you're in Dig DC, be sure to check out the Real Estate Plat Book Collection. This collection of real estate atlases now includes seven plat books, from 1874 to 1896. These real estate atlases have enormous research value. Plat maps convey important information about a property, such as the footprint, lot and building dimensions, and material. These maps can help you find old lot numbers, street names, and subdivision names. Studying plat maps over time gives a sense of the gradual development of neighborhoods and shows what existed before the current homes and buildings were built.
