After illustrating a series of humour books, Geisel decided to write a children’s book, which was reportedly rejected by nearly 30 publishers. After his chance meeting with a friend who was an editor at Vanguard Press, And to Think That I Saw It on Mulberry Street was finally released in 1937. The work centres on a young boy who transforms his ordinary walk home from school into a fantastical story. Later, however, he describes only the facts of his walk to his father, who frowns on the boy’s imaginative nature. Geisel used the pen name Dr. Seuss, planning to publish novels under his surname; the Dr. was a tongue-in-cheek reference to his uncompleted doctorate degree. However, his first book for adults, The Seven Lady Godivas (1939), fared poorly, and thereafter he focused on children’s books, which he preferred. According to Geisel, “Adults are obsolete children, and the hell with them.” What Was I Scared Of?: The tale of a character who repeatedly meets up with an empty pair of pale-green pants and has to learn to accept them. Geisel also wrote several books that were posthumously published under his most recognizable pen name, Dr. Seuss. Geisel's books and characters are featured in Seuss Landing, one of many islands at the Islands of Adventure theme park in Orlando, Florida. In an attempt to match Geisel's visual style, there are reportedly "no straight lines" in Seuss Landing.

In 2015, Random House Children’s Books posthumously published a new Dr. Seuss book, titled What Pet Should I Get?, after the manuscript and sketches were found by the author’s widow in the couple’s home. This Dr. Seuss collection was a series released by Random House. They are a video version of a "book on tape". None of these productions are animated. This section does not contain duplicate entries. While Horton Hatches The Egg, How The Grinch Stole Christmas, Horton Hears a Who, The Cat in the Hat, Green Eggs and Ham, and Because A Little Bug Went Ka-Choo! were adapted into full animation, they were also adapted into a non-animated production for this Dr. Seuss collection.

Adapted into a 1972 television special, a 2012 feature length CGI film, and a 2018 musical. It pretty much follows that format all the way through, and I have to say, they aren't the easiest rhymes to say! Some of them are absolute tongue twisters, which I think was deliberate. This super-simple, super-sturdy board book edition of The Eye Book--Dr. Seuss's hilarious ode to eyes--gives little ones a whole new appreciation for all the wonderful things to be seen. The first two Dr. Seuss Bright and Early Books and the final four Dr. Seuss Beginner Books are in one volume. Final Dr. Seuss book not illustrated by Geisel.
