Considering I work in two libraries I would say that my reading habit was how I found my way to my career path. Also patrons like seeing people at the desk reading. It is a natural point of conversation. It frankly surprises me the number of people I work with who are not big readers (more than one).

Where I get irritated is when people make the tired old joke that it must be nice to have a job where we sit around and read all day. "Bitch, you just caught me in the five minutes I had of downtime! I work!"
