Censorship and music/media (Ravindra/Bryan)

I have a list of afew books and copies of articles that I will send to DCE tomorrow.  It would help me to know a little more - are you looking at any specific time period?  any specific type of music (rock/rap) ?  lyrics?  ratings?  violence?
If you haven't narrowed it down, read through some of the articles and let me know if you'd like more info on any subtopics.
