You say libraries purpose is to help the community. If that's true, what you're saying makes sense. On the other hand, if their purpose is to promote literacy and reading, well, this is off mission.
I think of the former mission as more being a community center. My mother loves this form and spends a lot of time at her local library. I'm a curmudgeon and an intellectual snob apparently. I don't even like them having popular books, but I'm trying to be less rigid and more honest here and admit that some scope creep is probably healthy and the question is just where you draw the line.
