Nevins has annotated dozens of comics, starting primarily with a number of Elseworlds published by DC, most notably Kingdom Come and The Nail, covering in great detail the comic book, literary, popular cultural, and other sources of various plot points and featured characters. In the case of Kingdom Come, Nevins (and his irregular "divers hands" - his annotations are in large part a collaborative effort, inviting comment, correction and constructive critique) identifies most of the many featured characters from the future of the DCU, noting their predecessors and origins.

Nevins' most popular, in-depth and recent annotations, however, have focused almost entirely on works by Alan Moore for Moore's own America's Best Comics imprint, published until recently through the DC Comics imprint Wildstorm. Starting with the comic which most closely mirrors his own interests - the Victoriana/Steampunk/Alternate history/literary-mashup The League of Extraordinary Gentlemen, Nevins trawled the popular and not-so-popular literature of the past to compile (again, with help from the "divers hands") a thorough reference work to the first volume of Moore and Kevin O'Neill's masterpiece.

In large part due to Nevins' work annotating the first volume of LoEG, Moore has stated that he felt more comfortable alluding to ever-more obscure works - content in the knowledge that the reference would likely be caught and, therefore, made available to the casual reader. (Nevins' annotations are published for free online, while his LoEG annotations are also available in print from MonkeyBrain Books). This further helped encourage Moore to produce his literary-tour-de-force in The League of Extraordinary Gentlemen, Volume II: "The New Traveller's Almanac", a swift geographical tour of fictional places and events, referencing everything from Shakespeare to Lovecraft; obscure Chinese authors from the Han Dynasty, through Shelley and Lewis Carroll to Jorge Luis Borges and beyond. Covert references to Nevins himself can be found within the pages of LoEG Vol. 2 and the Black Dossier, while Moore has acknowledged in multiple interviews that he sees "these companion volumes as having a necessary organic place in the body of the work itself," effectively deputising Nevins as a partial collaborator.

In-between volumes of LoEG, Nevins has tackled Moore and Gene Ha's Top Ten, a superhero-police comic in which a powerful police precinct in Neopolis has to deal with various superhuman crimes. Nevin's interest in, and knowledge of the "Golden Age" of Superheros (and subsequent eras) aids him considerably in noting, as in his Kingdom Come annotations, the precedents and inspirations behind many of the characters featured. Nevins began annotations on the Top Ten spin-off Smax (by Moore and Zander Cannon) which were abandoned due to a number of rude, negative e-mail comments sent during this time. Nevins has subsequently provided annotations on Moore and Ha's 2005 Top Ten graphic novel The Forty-Niners, filling in some of the early history of the series, and Paul Di Filippo and Jerry Ordway's 2005 sequel mini-series Beyond the Farthest Precinct. Nevins also began to annotate Neil Gaiman and Andy Kubert's 2003 mini-series 1602 from Marvel Comics.

Nevins has also published Impossible Territories a book of exhaustive annotations for the 2007 LoEG graphic novel The Black Dossier.

For several years, Nevins has compiled - and made freely available - reference works on a number of inter-related subjects, including "The History of Timely Comics" (the company that would become Marvel), originally posted at the Avengers Assemble site of Van Allen Plexico, and various 'Guides to early Marvel Characters. has also compiled a more general reference guide which includes other companies' creations, entitled simply "The Golden Age Heroes Directory," his "Pulp and Adventure Heroes" Directory, and a guide to "Fantastic, Mysterious, and Adventurous Victoriana."

Nevins is also a contributor to/collaborator on the ever-expanding Wold Newton Universe, under the guidance of Win Scott Eckert at the Wold Newton Universe webpage. He has also written stories appearing in the Tales of the Shadowmen anthology series: "A Jest, To Pass The Time" from volume 2, "Red in Tooth and Claw" in volume 4, and "A Root That Beareth Gall and Worms" in volume 5.

Alongside his volumes of annotations on The League of Extraordinary Gentlemen (Heroes & Monsters and A Blazing World, respectively), Nevins has much expanded some of his online resources for print, authoring the World Fantasy Award-nominated The Encyclopedia of Fantastic Victoriana (left), the definitive guide on the strange and wonderful of that period. In May, 2007, critically-praised publisher of multiple popular-culture reference works McFarland published his Pulp Holdings Index, a listing of which issues of which pulp magazines are held in which American, Canadian, British, and European libraries. He revised his annotations for The Black Dossier into Impossible Territories, (MonkeyBrain Books in July, 2008), which will be the third companion to The League of Extraordinary Gentlemen by Alan Moore and Kevin O'Neill.

Nevins has also been published in Steve Jackson Games' Pyramid, and more recently, has written a series of essays, one for each issue of Ed Brubaker and Sean Phillips' comic Criminal

He is also working on adapting his "Pulp Heroes" resource into the Encyclopedia of Pulp Heroes, which should be published sometime during 2010/11, as well as his companion superhero reference work, the Encyclopedia of Golden Age Superheroes, a descriptive listing of every superhero published between 1935 and 1949. He is also writing Strange Tales of the Century, for Evil Hat Productions, a supplement to Evil Hat's RPG Spirit of the Century that should be finished around Summer/Fall 2009. It will deal with pulp fiction from around the world and outline the various archetypes and the historical setting.
