Q. Are there Sanborn Maps for College Park that date before 1939?

Hello, 

Unfortunately, there are no Sanborn maps of College Park before 1939.  College Park appears in the Washington Suburban, Volume 2 edition beginning in 1939. 

The Library of Congress has a useful website where you can search for Sanborn map coverage.  Since the Digital Sanborn Maps database was created by scanning the Library of Congress's microfilm, it also essentially lets you know what is in that database too. Please go here to pursue this further.
