What did I count as a graphic novel? Well, I was kind of haphazard to be honest.
Things that counted:
- Gen13 Bootleg: Grunge: the Movie - It only collects three issues.
- Tell Me Something by Jason - It's only like 48 pages long.
- The Viz 2015 sampler
- Image Firsts Compendium Vol. 1 - A bunch of #1s. I think these are literally just the $1 issues with the staples cut off and bound together.
- Costume Quest: Invasion of the Candy Snatchers - The digital version I have is 59 pages, which includes a bunch of pages which aren't comics.
- Things I had read in previous years and reread in 2015.
- Station 16 - Only 54 pages long.
- Books I read digitally (on Hoopla or otherwise).
- Collections of comic strips. - Just Cul de Sac I think.
Things that didn't count:
- Single issues that made up a storyline that have been collected. - Mostly lots of old X-Men comics.
- Island - The anthology that Brandon Graham puts out. It's a magazine?
- Other single issues that were pretty big. - Marvel Super-Hereos #2 Summer Special from 1991 claims to be 80 pages long on the cover. (It is terrible by the way.)
- Prestige format things that were 40-60 pages or so long. - JLA/WildCATs, some Sabertooth thing, some other stuff.
- Webcomics I read online.
- Team Cul de Sac: Cartoonists Draw the Line at Parkinson's - A bunch of this is comic strips, but I decided not enough was.
- The volume of the Authority I read because it had an annual and a story that weren't collected in The Authority by Warren Ellis/Mark Millar collections.
Things I read that collected other things but only counted as one thing:
- Essential Marvel and DC Showcase Presents volumes. Collect various Masterworks/Archives, but only count as one each.
- BPRD: Plague of Frogs Omnibus collect three smaller volumes, but I only counted once.
The 500 does include both manga and non-manga , and here's the breakdown.
As you can see I read far more non-manga (441) than manga (59). If you look at the monthly stats you'll see that while I started fairly strong in regards to manga (11 read in January), I soon dropped off (5 read October-December, none read in June!).
Manga I read were very heavily series based. Of the 37 published by Viz that I read, 24 of them were 20th Century Boys. All six of the Tokyopop titles were King of Thorn.
For non-manga I read far too many Marvel comics.
The publishers from whom I read ten or more titles were
Dark Horse: 45
"Other" consists of every publisher from whom I read only one book.
17 of Boom's titles were Irredeemable/Incorruptible (and I read all of those in January/February. Boom and Marvel were almost on par for the first two months).
If you include Wildstorm and Vertigo with DC they would have 48 books and be the second largest publisher.
* Wildstorm is kind of a special case, since I counted things that had been published under other imprints for them. Two volumes of Gen:13 Bootleg were published by Wildstorm when they were at Image. The volumes of Stormwatch and The Authority I read (that reprinted work originally published by Wildstorm) I counted as Wildstorm, even though they were printed by DC. The New 52 Stormwatch was set in the mainstream DC universe, so they were included in DC's number.
Here's a chart (with some terrible colours, thanks Google...) showing how much of each publisher I read each month. This combines the manga and non-manga lists, so Dark Horse gains 3 books, while Fantagraphics, DC, and NBM (not on this list) gain 1 each. Viz moves into 4th place, and DC is now tied with Boom. Fantagraphics also joins the "10 books" club.
