New York Public Library Digital Gallery

This massive collection presents more than 550,000 images relevant to both U.S. and world history, from the earliest days of print culture to the present. Resources consist primarily of historical maps, posters, prints and photographs, illuminated manuscript pages, and images drawn from published books.

For browsing, the materials are divided by subject heading, library of origin, and the name of the item's creator and/or publisher. They are also sorted by collection: Arts & Literature; Cities & Building; Culture & Society; History & Geography; Industry & Technology; Nature & Science; and Printing & Graphics. Within these broad headings, images are further subdivided into more specific groupings, for example, Indonesian dance, dress and fashion, Civil War medical care, and New York City apartment buildings. All images can be downloaded and are accompanied by detailed source information, but users will have to turn elsewhere for historical context.
