Alfred Stieglitz' quarterly journal Camera Work can now be found on-line. The on-line archive includes issues from #1, Jan 1903 to #50 Jun 1917. I believe this is the entire run of the journal. This era is when photography was coming into its own as a serious art form and this journal was an advocate and a pioneer for that position (hence why I post here in Philosophy). If you're looking for something to do this winter each of these issues make for fascinating, educational, and inspirational reading and viewing. Even the ads for photographic equipment at the end of each issue keep my attention. Here is the link to the on-line archive: Camera Work.
