Maurice Sendak needs little introduction. He is the winner of the Caldecott, the Hans Christian Andersen Medal, and dozens of other honors for his innovative and thoughtful books for children. Hal Marcovitz has done a fine job of presenting the artist and his causes. Marcovitz approaches his subject through his causes, opening with Sendak's take on homelessness in "We Are All in the Dumps with Jack and Guy." Interviews are interspersed with bits of biographyincluding Sendak's more recent preoccupation with operaand sidebars emphasize Sendak's literary and artistic influences (the Brothers Grimm, William Blake, Mozart, the Holocaust). Perhaps the most interesting chapter addresses the issue of censorship and the pros and cons of putting diapers on Mickey in "In the Night Kitchen." Part of the "Who Wrote That?" series, the back matter contains notes, bibliography, index, and chronologies of Sendak's life and published works. The end result is a very good effort, lacking only one obvious thingimages of Sendak's books and art.
