Yale Photonegatives Collection

Avi sez: "Don't know if you've had this before, but this database is an amazing photographic (and artistic) treasure of America's people and places at the turn of the previous century. Unfortunately, there is no index of the contents so you have to try your luck with keywords, which almost always turn up interesting finds. For example try typing in 'Indian' and see what happens! My favorite entries are 'Garden' and 'Gurdjieff'!" Link
