Book excerpt: Literature Suppressed on Social Grounds, Revised Edition discusses writings that have been banned over the centuries because they offended or merely ignored official truths; challenged widely held assumptions; or contained ideas or language unacceptable to a state, religious institution, or private moral watchdog. The entries new to this edition include the Captain Underpants series, We All Fall Down by Robert Cormier, and Jake and Honeybunch Go to Heaven by Margaret Zemach. Also included are updates to the censorship histories of such books as To Kill a Mockingbird and Of Mice and Men.
