Stumbled across this link, Forbidden Library: Banned and Censored Books. Take a look at a few of these that were banned:

Anne Frank: The Diary of a Young Girl. Challenged in Wise County, Va. (1982) due to “sexually offensive” passages. Four members of the Alabama State Textbook Committee (1983) called for the rejection of this book because it is a “real downer.” …. War and genocide usually are such downers, aren’t they?

My Friend Flicka. Removed from fifth and sixth grade optional reading lists in Clay County, Fla. schools (1990) because the book uses the word “bitch” to refer to a female dog, as well as the word “damn.” …. Okay, first off, “bitch” IS a female dog! Second, 95% of kids have heard the word “damn” before (does anyone actually say “Damn!”? I don’t). The 5% who haven’t heard it are Amish.

The Lorax, by Dr. Seuss. Challenged in the Laytonville, Calif. Unified School District (1989) because it “criminalizes the foresting industry.” … and the Cat in the Hat promotes animal cruelty?

Zen Buddhism: Selected Writings. Challenged at the Plymouth-Canton school system in Canton, Mich. (1987) because “this book details the teachings of the religion of Buddhism in such a way that the reader could very likely embrace its teachings and choose this as his religion.” The last thing we need are a bunch of peaceful Buddhists running around. The horror.
