Comic book editing is most analogous to music producing -- they're both jobs nobody understands. But if a writer, artist, colorist and letterer are a band then the editor is the producer, and together they try to make the best versions of the songs the band's come up with, often with a view to creating a full-length album. In comics, the songs are single issues and the albums are what're popularly known as graphic novels.
This is an alphabetical sorting of all the graphic novel collections of stories I've worked on as an editor at DC Comics. I refer to this body of work as DC Khomics because it makes my coworkers really mad.
