The only cons I get to go to are librarians' conferences, such as the annual meeting of the Texas Library Association. The cosplay efforts are generally...pathetic.
But that might change! The annual conference of the American Library Association will convene in Chicago from June 27-July 2. There will be geek-themed events during that time for what the organizers are calling GraphiCon:
For the second year, GraphiCon will inspire ALA Annual Conference attendees to innovate and raise the profile of graphic novels and comics in their library or school. A range of programs and author events, plus “Artist Alley,” the Graphic Novel Pavilion and Graphic Novel Stage in the exhibit hall will offer information and creative inspiration, as well as chances to ask questions and discuss ideas.
Amanda Brennan, the resident librarian at Know Your Meme, tweets "Does this mean I can cosplay ALA?!" Definitely.
