Difference between picture book, graphic novel and comic book?

What there is more of in a graphic novel, writing or art, is really unanswerable. There is a lot of both and generally the two do intertwine so some aspects of the drawing can be called writing.

A picture book is a general term, and includes coffee table books. Obviously it includes both graphic novels and comics and much more -- such as Lynd Ward's novels in woodcuts from the thirties which influenced a lot of comic artists who came in in the seventies. A comic book is a magazine which either serializes a story or presents a story which is part of a series. A graphic novel is a longer piece which presents a self-contained story which may or may not be part of a series. To use a Belgian example, Herge's classic comic Tintin was originally serialized in the fascist newspaper le XXme Siecle then after world war II in its own magazine, Tintin, with other series such as Bernard Prince. In the US it was serialized in Childrens' Digest, but as each episode finished serializing in France it was collected into an album -- essentially a graphic novel but they were called albums till the term came into broad use and that was indeed how many of us discovered him. These days they can be had in collections which present two adventures at once. The Watchmen and, I believe League of Extraordinary Gentlement were published as comic books before they were Graphic Novels.

Back when we used to call the Undergrounds Comix -- Gilbert Shelton, Spain Rodriguez and R. Crumb -- but they were comic books. Underground Comic books. So comics are not MORE for kids. However the Industry has coopted most of what the undergrounds did and guys like Spain work on-line while Shelton lives in France (as does Crumb I believe).

In other words between the second two there is a difference in format, not content, and the first is something else.

Comic Book Vs Graphic Novel

Binding Comic books are the issues that look like a magazine where Graphic novels are a bunch of the issues put together into one volume. Graphic Novel is more of a fancy subtype of comic book, but it fine to call a graphic novel a comic book There is a bit of a gray area There are some shorter graphic novels that never had a comic book stage and I'm sure you've seen book anthologies of strips like Peanuts or Calvin & Hobbes, those would not be consider Graphic Novel because well it's not a novel

I was curious on the answer too
