This searchable repository of over 1.6 million high quality digital images offers tools for viewing, sharing, and saving visual materials. Although its strengths are visual art and architecture, Artstor includes images that are useful in both the humanities and the sciences.
More than 30,000 digitized images from books, magazines, newspapers, original photographs, prints and postcards from the Picture Collection at the NYPL Mid-Manhattan Library. Most images date from before 1923.
The World Digital Library (WDL) makes available free of charge and in multilingual format, significant primary materials from countries and cultures around the world.
