The Young Adult Library Services Association (YALSA) has their nominations for their annual great Graphic Novels for Teen list up. The list of recommended graphic novels and illustrated nonfiction for those ages 12-18 is prepared yearly. A shorter list of recommended titles will be made later in the year, with a Top Ten list released later in the year.
There are over a hundred titles on the list, covering all major genres, from manga and literary to mainstream.
2009’s list can be read here.
