Manga, Collecting

Comic book-loving librarians should refer to their beloved medium as anime and/or manga.  Doing so will cause your library colleagues to suddenly recognize your interest as a legitimate genre and give you lots of money to build a collection at your library.  If this doesn't work,  you can always return to your strategy of drawing half-naked, doe-eyed Japanese girl samurais and posting them in your cubicle.

Graphic novels, Embracing

Every library has at least one librarian who is a graphic novel enthusiast. This person will argue vehemently for a new graphic novel collection for your library. Give him a paltry budget to spend each year just to shut him up. It will be money well spent.
