Someone has been censoring cuss words in books at the Maury County Public Libary.  News 2 reports that 50 to 100 books have been defaced.  Nobody knows who's doing it, but you can see the words...mostly the F-word... crossed out in pencil, ink or white-out.  The Library Director is not amused by mystery censor. She says the computerized check out system makes it hard to track who the book vandal might be.
