How to Find Maps

Mapmaking in Maryland has a long and honored history.  The H. Furlong Baldwin Library has both individual maps and atlases (bound, published collections of maps).

Finding Maps

Individual maps are part of Special Collections and may be requested in the McIlvain Special Collections Reading Room.  You may identify maps by doing all of the following:

1. Checking the Combined Map Inventory.

2. Checking the list of maps which can be found in the Library's rare book collection.  The list is available in the McIlvain Special Collections Reading Room, where you may request the books.

3. Checking the subject index to maps, a card index which includes many maps not listed in the Combined Map Inventory.  This index can be found in the card cabinet in the Microfilm Reading Room.  The index is labeled "Maps A-Z."

4. Checking the plat card index, if you are looking for a plat of a specific land tract.  The plat index can be found in the card cabinet in the Microfilm Reading Room and is labeled "Plats A-Z."

Finding Atlases

Atlases are part of the collection of the Rhodes Local and Family History Reading Room.  The easiest way to find atlases is to do a keyword search in the online catalog for atlas.  If you have a call number for an atlas listed in our catalog, but you cannot find it, please request it at the reference desk in the Rhodes Reading Room.

In addition to numerous county atlases, here are some of the major atlases which the Library owns:

Baltimore City

Atlas of Baltimore and Its Environs, 1876, aka the Hopkins atlas, is exceptionally useful for Baltimore City north of North Avenue.  Sanborn maps (see below) did not cover this area until the 1930s.

Atlas of the City of Baltimore, 1885, 1896, 1906 aka the Bromley atlases, have much more detailed building information for the city than the earlier Hopkins atlas but less information about surrounding areas.  The numbers on the buildings indicate their height, and colors represent building materials.
