New York Public Library, has recently made over 20,000 historical maps from its database free to access and created an entire website called Map Warper where users can access all the maps, but also “digitally align (“rectify”) historical maps from the NYPL’s collections to match today’s precise maps”.
This institution announced last November 2013 that they had digitized over a thousand videos in the Jerome Robbins Dance Division Moving Image Archive and created another web page where you can browse or search the collection.
