It’s encouraging to see libraries and museums beginning to make public domain images freely available, increasingly providing high-resolution scans or photos for downloading. Historically, they have guarded images of objects in their collections as a private source of income. Count the New York Public Library among the honorable elite who have made their pd images available to be shared. The library has just put up more than 180,000 images in hi-res free for the downloading. Highlights of the collection include photographs from the Farm Security Administration and Works Progress Administration, Medieval and Renaissance manuscripts, Walt Whitman papers (1854–1892), and early film shorts.
