Public Domain Maps in New York Public Library Collection

Jonathan Crowe, the writer of The Map Room blog, highlighted the New York Public Library Public Domain Documents today.  There are over 180,000 documents, and over 21,000 maps in this collection, all available to view online and to download for further review.

I chose the "Original" button, and downloaded the 1843 map to my computer.  It was 5,699 kb.
