LIFE photos available on Google
LIFE was one of the world's few magazines with a heavy emphasis on photojournalism.
However, it ceased publications last year, citing changing demographics, lack of interest, and the Internet as the reasons... and it is now reborn thanks to Google.
It seems like Google is really delivering the goods today, wonder what else they are going to release.
EDIT : If you liked the photos in the Vietnam War series, I recommend you a photojourn book, which is astounding in depth and quality.
