When I was a kid, my father brought home from I know not where an enormous collection of National Geographic magazines spanning the years 1917 to 1985. I found, tucked in almost every issue, one of the magazine’s gorgeous maps—of the Moon, St. Petersburg, the Himalayas, Eastern Europe’s ever-shifting boundaries. I became a cartography enthusiast and geographical sponge, poring over them for years just for the sheer enjoyment of it, a pleasure that remains with me today. Whether you’re like me and simply love the imaginative exercise of tracing a map’s lines and contours and absorbing information, or you love to do that and you get paid for it, you’ll find innumerable ways to spend your time on the new Open Access Maps project at the New York Public Library. The NYPL announces the release with the explanation below:

The Lionel Pincus & Princess Firyal Map Division is very proud to announce the release of more than 20,000 cartographic works as high resolution downloads. We believe these maps have no known US copyright restrictions.* To the extent that some jurisdictions grant NYPL an additional copyright in the digital reproductions of these maps, NYPL is distributing these images under a Creative Commons CC0 1.0 Universal Public Domain Dedication. The maps can be viewed through the New York Public Library’s Digital Collections page, and downloaded (!), through the Map Warper.

What does this mean? Simply put, “it means you can have the maps, all of them if you want, for free, in high resolution.” Maps like thatabove, of New York’s Central Park, issued in 1863, ten years beforeFrederick Law Olmstead and Calvert Vaux completed their historic re-design.
