Dear Sandeep - I found the following book extremely helpful Ulf-Dietrich Reips is on this list and probably too modest to plug his own book! Batinic, B., Reips, U-D., Bosnjak, M. (Eds). 2002. Online Social Sciences. Seattle: Hogrefe & Huber. I will have a review of it out shortly, but note that most of the research methods here are detailed from the social cognitive and psychological perspective. There's 26 chapters, so plenty of material there in a variety of online settings (OLP - online panels, MUDs, Usenet, online dating, online experiments, online personality tests, etc.) Also, most chapters include the stats that compare their online vs. pencil/paper findings. The URLs to the research sites are all listed. A very very useful reference even if your brief is outside of psychology.
