Hi: I have found a scarcity of print sources on this topic; I am not sure if it is because the topic is new, or if it is too cynamic to hold still long enough to make it to print. Some of the websites I have found helpful are cybertower.com, metanoia.org, psychnet and the apa site. I have been using these sites as sources for a graduate level paper on psychotherapy and the net. I am sure there are more. Other places you might look are government papers on the allowance of encription and confidentiality. Good luck on your paper. Jack
