A friend of mine who is a middle school librarian sent me the above bookmark the other day, figuring I'd get a kick out of it since I work in a library and am a comics fan. Definitely fun stuff, courtesy of the ALA. There's a poster, too, if that's more your style.
And yes, I know, technically Barbara Gordon isn't Batgirl anymore, but let's not get all fanboy on this one. It's a fun idea, and the librarians need all the positive media portrayals they can get. I mean, all we've got is the Action Figure Lady, Rupert Giles and Yomiko Readman (she counts, right?). Every little bit helps.
