www.bookcrossing.com (New Delhi)
First off I don't know how many of you in the Delhi area would be interested in this site [ Protected content ] or using this service but you're on internations.org so I suspect that there is a certain amount of interest in knowledge and information/resources sharing. I was checking out this site and unfortunately there are no areas in Delhi where one can trade books. However, in light of that fact, I thought it would be cool to start one assuming there is enough interest! Looking forward to hearing from you guys!
All the Best,
