[Air-l] Reading on anonymity, gdss

I'm looking for a good reading for undergraduates on the impact of anonymity in CMC on communication and other behaviors, and also one on Group Decision Support Systems. I know of a number of articles that discuss anonymity along with other things, but I wanted one that brings that work together. With GDSS there are some books but I'd like something shorter. I'm interested in something that is quite recent (say 5 years or so) and can give a bit of state of the art on the subject. Thanks. /Caroline ------- Caroline Haythornthwaite Graduate School of Library and Information Science University of Illinois at Urbana-Champaign
