The Cornell University Library, as part of its mission to bring the library to its users where ever they may be, has put up on Flickr a selection of images from one of its prize collections, the AD White Architectural Photograph collection. All the photographs currently available are of buildings in Europe. Because Flickr Commons is not currently accepting new collections, this is in regular Flickr. They are licensed at the most general level Flickr allows (Attribution), and each image contains the following note:
There are no known U.S. copyright restrictions on this image. The digital file is owned by the Cornell Univeristy Library which is making it freely available with the request that, when possible, the Library be credited as its source.
Everybody if invited to visit Flickr and add tags, notes, and comments to these fine images.
