Comics and Sequential Art is a book by American cartoonist Will Eisner that analyzes the comics medium, published in 1985 and revised in 1990. It is based on a series of essays that appeared in The Spirit magazine, themselves based on Eisner's experience teaching a course on comics at the School of Visual Arts. It is not presented as a teaching guide, however, but as a series of demonstrations of principles and methods. A 1990 expanded edition of the book includes short sections on the print process and the use of computers in comics. Eisner followed with a companion volume, Graphic Storytelling and Visual Narrative, in 1996. Source: Wikipedia (en)
