FAHRENHEIT 451: This book was expurgated at the Venado Middle School in Irvine, California (1992). Students received copies of the book with scores of words — mostly “hells” and damns” — blacked out… After receiving complaints from parents and being contacted by reporters, school officials said censored copies would no longer be used.

This is an example of an expurgated text.
