In 1930, Bibo and Lang of New York published the first Disney-licensed publication, Mickey Mouse Book, which featured the story of how he met Walt Disney and got his name.
The Book was soon followed a year later by a second book, the first one printed in hardback The Adventures of Mickey Mouse Book I, published by the David McKay Company, an illustrated storybook that presented stories with Mickey, Minnie and a variety of obscure characters from the original cartoon assemble (among them, Horace Horsecollar and Clarabelle Cow) and mentioned and featured a character bearing the name "Donald Duck", just three years before the official Donald first appeared in the Silly Symphony cartoon The Wise Little Hen (1934).
The novelization of Lady and the Tramp written by Ward Greene was incidentally published in 1953, two years before the film's release.
The following is a list of books based on Walt Disney Company media, from the classic cartoons and characters such as Mickey Mouse and Donald Duck, the Disney anthology television series, Disney Channel Original Movies, spin-offs from the DCOMs such as the High School Musical film series, Stories from East High or Camp Rock: Second Session, Disney Channel Original Series, and films from Walt Disney Pictures and its respective franchises (Winnie the Pooh, Herbie, Tron, The Mighty Ducks, Pirates of the Caribbean, etc.).
As a continuity reference, most of the novels will carry the term on their respective front cover "The Book of the Film".
