I have been messing with this program, thanks to a fellow friend of mine suggesting this to me. Zotero is basically a research management program that organizes and also retrieves metadata for you, which I find quite neat.
The reason I'm dropping by to mention this is because I think it might be useful for those whom are also interested in researching, whether about pedophilia, and/or other topics.
Simply searching for the term "Zotero" will hit you up with the program. For those that do try it out, I hope it helps you out the same way it does to me. Also, yes, it's free and Open-Source.
