Many of Silverstein’s books have been banned quite
frequently. Along with A Light in the Attic, number 51 on the American Library
Association’s list of 100 most frequently challenged books: 1990–1999, are two
other Silverstein classics, The Giving Tree and Where the Sidewalk Ends. These
are books most of us are familiar with and yet they were all challenged at one
time or another because of controversy surrounding some of their content. So
why has Silverstein’s work been challenged so often?
