Anyone may Google banned book week for information on how you can get involved in your area.
I have been a fan of LibraryThing (librarything.com) for over a year. I can spend hours finding undiscovered books through tags. I searched for "banned books" and noticed a book I haven't read before, 100 Banned Books: Censorship Histories of World Literature by Nicholas J. Karolides. This reference discussed titles that have historically been challenged or banned across the globe.
The Banned Book Club is a blog that continues to offer conversations about challenged and banned books. It is moderated frequently and offers membership. They have several interesting discussions all pertaining to the important topic of book censorship. The RSS feed can be found on the upper right hand corner of this page.

Libraryland Roundup is a great blog for "collection managers, reference providers, reader's advisors, the technically inclined, and other denizens of libraryland." It was easily accessed using blogsearch.google.com
