Free Maps From the New York Public Library
Last year we saw the Getty Museum make thousands of high-resolution images freely available for download through their Open Content program. And now here’s another great freebie: the New York Public Library’s Open Access Maps.
Altogether, more than 20,000 high-resolution historic maps are downloadable and free for any use under the Creative Commons Public Domain Dedication. Many of the historic maps are also rectified (matched up to modern maps).
