'Hop On Pop' is Published

A popular choice of elementary school teachers and children's librarians, Hop on Pop ranked sixteenth on Publishers Weekly's 2001 list of the all-time best-selling hardcover books for children.

One of its most notable advocates is former United States First Lady Laura Bush, who listed it as her favorite book in a 2006 Wall Street Journal article. "It features Dr. Seuss's typically wonderful illustrations and rhymes, of course, but the main thing for me is the family memory—the loving memory—that the book evokes of George lying on the floor and reading it to our daughters, Barbara and Jenna. They were little bitty things, and they took Hop on Pop literally, and jumped on him—we have the pictures to prove it," she wrote.

One of Geisel's manuscript drafts for the book contained the lines, "When I read I am smart / I always cut whole words apart. / Con Stan Tin O Ple, Tim Buk Too / Con Tra Cep Tive, Kan Ga Roo." Geisel had included the contraceptive reference to ensure that publisher Bennett Cerf was reading the manuscript. Cerf did notice the line, and the poem was changed to the following: "My father / can read / big words, too. / Like... / Constantinople / and / Timbuktu."
