'''Rosemary Wells''' is a prolific creator of children's picture books and has also written for older audiences. Her two most popular franchises, which have also been adapted for television, are ''Literature/MaxAndRuby'' and ''WesternAnimation/TimothyGoesToSchool''. Some other popular titles by her include the ''Bunny Planet'' books, the ''Edward the Unready'' series (later rereleased as eBooks under the banner "Edward Almost Ready"), the ''[=McDuff=]'' series and ''Emily's First 100 Days of Kindergarten''. Her nonfiction titles have included ''Help Children Cope with Divorce'' and ''Getting to Know You: Rodgers and Hammerstein Favorites''. Some of her works titled at older audiences include ''Mary on Horseback'' and ''The Miraculous Tale of the Two Maries''. In all, she has written well over 100 titles. Her newest series, about a group of young alligators, is called ''Kindergators''.

Her very first title, published in 1972, was ''Unfortunately Harriet''. It is currently out of print. Her second title, published a year later, was the much more well-known ''Noisy Nora'', which remains in print to this day, with Nora becoming one of the characters on the ''Timothy Goes to School'' television series.

She was also involved in the production of the ''Max & Ruby'' and ''Timothy'' television series.

!Tropes often featured in Wells's works include:

* AnAesop: Though not always
* AnimatedAdaptation: Those that haven't been made into television series have often been adapted as read aloud storybooks for home video, sometimes with animation.
* CarnivoreConfusion: The picture book ''First Tomato'' from the ''Bunny Planet'' series describes a group of bunny-people children being served bologna sandwiches, which greatly depresses the main character, as this is her least favorite lunch. Another character in the same series has to suffer through a dinner of cold liver chili.
* EveryEpisodeEnding: Every installment of the ''Voyage to the Bunny Planet'' books ends with the star character observing the Bunny Planet in the night sky and marveling "It was there all along!"
* FantasticRacism: Used in ''Yoko'', in which the titular character, a Japanese kitten, is ostracized for eating sushi at lunch.
* FunnyAnimal or TalkingAnimal
* HalfDressedCartoonAnimal
* InvisibleParents
* MouseWorld: Often with rabbits
* RascallyRabbit
* ReptilesAreAbhorrent: Pleasantly averted in her ''Kindergators'' series, which actually features anthropomorphic alligators. Some of the children behave badly at times, but this only because they are young and still learning; none of them are actually truly mean or nasty.
* SliceOfLife
