Although not officially either a librarian or a library patron, the new Geekman action figure might represent another breed of information maniac.
This story from the LA Times (registration required...but here's another w/o registration from the Seattle Times) portrays Geekman as "altogether hip." When asked what his hero's superpowers are, Kris Schantz, founder of Happy Worker toys and creator of GeekMan, listed "opposite-sex repulsion, analytical reasoning, the ability to create technical acronyms and less-than-ideal personal hygiene."
Geekman is available at local toy stores and on the web. This reporter thinks he'd play well with the loveable Nancy Pearl shushing librarian doll.
