How about "Graphic Biography?"
is this so hard?
I submit that it's ONLY in the "graphic novel" section, because there aren't enough to make a whole section of it. If you had a thousand biographies in that format, it would have a "graphic biography" section.
I have no problem calling it "comics" because Eisner's term "Sequential Art" and McCloud's term "Sequential Storytelling" too loaded and appears to exclude certain comics (like the Far Side, which was rarely "sequential")
But novel seems entirely too loaded.
Besides, my REAL contention is that they are not replacing the novel. That's a ridiculous concept. Sure the number of comics published as books instead of monthly serials is climbing, but that hardly means that the art of the prose novel is dying off or being reduced in importance. This is not a trend that is real. And that, to me, throws into question anything else the article says if it is, as you say, about graphic novels replacing prose novels.
