Dr. Seuss bibliography

Theodor Seuss Geisel, better known as Dr. Seuss, published over 60 children's books over the course of his long career. Though most were published under his well-known pseudonym, Dr. Seuss, he also authored over a dozen books as '''Theo. LeSieg and one as Rosetta Stone'''. As one of the most popular children's authors of all time, Geisel's books have topped many bestseller lists, sold over 222 million copies, and been translated into more than 15 languages.[1]  In 2000, when Publishers Weekly compiled their list of the best-selling children's books of all time; 16 of the top 100 hardcover books were written by Geisel, including Green Eggs and Ham, at number 4, The Cat in the Hat, at number 9, and One Fish Two Fish Red Fish Blue Fish, at number 13, and Dr. Seuss's ABC. In the years following his death in 1991, several additional books based on his sketches and notes were published, including Hooray for Diffendoofer Day! The Hoober-Blob Highway, Gerald McBoing Boing!, and Daisy-Head Mayzie. Although they were all published under the name Dr. Seuss, only My Many Colored Days, originally written in 1973, was entirely by Geisel.
