> "any action taken against a book based on its content and as a result of parent or community challenges, administrative decisions, or in response to direct or threatened action by lawmakers or other governmental officials, that leads to a book being either completely removed from availability to students, or where access to a book is restricted or diminished."

Though this is a fascinating definition.. anytime, anywhere says "no thanks" to carrying a book outside of purely budgetary or physical space limits, it is now a "ban".

The more fascinating question would be discovering the boundary of what PEN, et al consider a "good ban" because I bet we could come up with a few.
