I was recently contacted by Hans IJzerman, Editor-in-cheif of in-mind.org, regarding their excellent online article repository. It is basically a social psychology site, containing articles from some of the stalwarts in social psychology like Phillip Zimbardo (BTW, the Phil Zimbardo article is also available on the excellent Situationist blog).
The site, though, requires free registration for reading the articles. One of the articles I found interesting was on evolution of religion, and one of the co-authors was Hans himself. There are plenty of other interesting articles , so head over to have a look.
