A friend of mine let me know about this NYTimes article about Life Magazine's photo archive posted on Google Images. It's a giant jumbled mess you can't flip through quickly. Lame and useless categories. The author compares the experience to rifling through a disorganized box of photographs rather than organized albums.
Check out Google's Life archive for yourself and see what you think... I haven't played with it yet.
The above cover is one of Bill Eppridge's many amazing shots. I wonder what he has to say about this.
