NYPL Puts 20K Historical Maps Online

[Morgyn]

All these maps are available digitally and are in the public domain. There’s even a tool that “aligns historical maps with current maps”.

Through these projects, we’ve built up a great collection of: 1,100 maps of the Mid-Atlantic United States and cities from the 16th to 19th centuries, mostly drawn from the Lawrence H. Slaughter Collection; a detailed collection of more than 700 topographic maps of the Austro-Hungarian empire created between 1877 and 1914; a collection of 2,800 maps from state, county and city atlases (mostly New York and New Jersey); a huge collection of more than 10,300 maps from property, zoning, topographic, but mostly fire insurance atlases of New York City dating from 1852 to 1922; and an incredibly diverse collection of more than 1,000 maps of New York City, its boroughs and neighborhoods, dating from 1660 to 1922, which detail transportation, vice, real estate development, urban renewal, industrial development and pollution, political geography among many, many other things.

You can download high-res images and use them however you want.
