Nevins has annotated several comics, starting with a number of Elseworlds published by DC Comics, including Kingdom Come and .
''The League of Extraordinary Gentlemen''
Nevins also annotated many of Alan Moore's for his America's Best Comics imprint, starting with The League of Extraordinary Gentlemen. Moore said of Nevins' work, "It was only when someone finally conveyed these internet postings to me... that I began to understand the invaluable asset that Jess represented... I realised that if we had tracking down all of the references for the readers, then we could be as obscure and far-reaching as we wanted...", Moore later said Nevins' work helped inform The League of Extraordinary Gentlemen, Volume II: "The New Traveller's Almanac": "The patient work contained within this current volume has played an important part in the construction of this vast, imaginary global edifice that we're constructing... ", Moore sees "these companion volumes as having a necessary organic place in the body of the work itself."
