So...As you can see, I tend to binge on the works of kidlit authors, and it helps that kidlit authors tend to pump out so many books in such little time!
On the other hand, the MG/YA section contains authors like Stine and Martin, whose series were long-runners in the 80s and 90s but eventually switched to ghostwriters, unless I'm very much mistaken. There's a huge jump between those two and the rest of the authors on the MG/YA list because the rest of the authors, with the exception of Ben M. Baglio, tend to write series that have definitive ends. Caroline B. Cooney, meanwhile, is the only one on that list from whom I've read mostly standalones.
In the adult fiction and nonfiction category, I could only come up with five authors. I expected more, but I suppose it makes sense; when it comes to kidlit, MG, and YA, I tend to read long series or even binge-read extensive libraries such as the Berenstain Bears. But when it comes to adult fiction, I tend to read either standalones or short series. All the authors on the list wrote short series of three or four books that I read in their entirety. The only exception is Dan Brown, who I've read two standalones from and three Langdon novels.
It looks like I definitely need to step up my adult fiction series reading, and maybe spend more time seeking out kidlit authors who only have a book or two under their belts.
