Sometimes these book-vandalism events reach epidemic levels. The Metro Toronto Library reported in 1975 that within one month over 200 reference books were "torn beyond repair."[9] In 1995, twenty California libraries were plagued by a serial "book slicer", removing pages from modern poetry collections causing over $10,000 in damage to over 200 books.[10] In Decatur, Alabama, 500 children's books were damaged by book slicing, with an estimated cost of $15,000.[11] Other books vandalized by razoring pages in Decatur, included books for adults on coaching children and also on books about sex.[12]
