Here’s a list of the major comics and graphic novel publishers exhibiting at the American Library Association Annual Conference in Washington, DC, this weekend.  This list is not exhaustive…many publishers offer the occasional graphic novel in their catalog, and all of the major publishers have graphic novel imprints as part of their larger catalog. If you’re there, try and wander every aisle…you never know what you’ll find!
ṦẄÊ̄ḜṮ ⱩĬŖḂɎ ƘɌÃČḴḸἚ! For $75, you can buy an “exhibits only” pass, and spend the entire show immersed in a great trade show with lots of programming offered at the many stages! (I’ll be posting schedules for all that soon.) Lots of authors signing books (some of them free!), lots of fellow bibliophiles, and the lines, which can be long, are nothing compared to San Diego or New York!
Here are the hours:

Friday, June 21: 5:30pm – 7:00pm – Opening Reception on the Exhibit Floor – For full conference registrants only
Saturday, June 22: 9:00am – 5:00pm
Sunday, June 23: 9:00am – 5:00pm
Monday, June 24: 9:00am – 2:00pm – Closing Events on the Exhibit Floor

This is a general map, and not definitive, as Papercutz and the mini gaming tables aren’t highlighted. (That’s listed under the “Gaming Grove” pavilion.)
But this is the general area for all sorts of geekiness! (Techies should check out the Glass Room Experience located between the Graphic Novel-Gaming stage and the Zine Pavilion, plus the Maker Space.)

Here’s the general info for the Exhibits Hall, and a dynamic map can be found here.
