Are you new to the skeptic movement?  Are you looking for material to educate others about skepticism and critical though?  Need a refresher?  The Skeptics Society has a new Skepticism 101 resource section of their website.  It is a collection of recommended books, courses, papers, presentations, etc.  The material can be used in classes or for self-study.  The collection can be searched by topic, by resource type, by academic discipline, and by academic level.  Check it out.

There is also extra background information about the resource center from Michael Shermer in his blog post, How to Learn to Think Like a Scientist (Without Being a Geek) .
