Since when are public libraries responsible for improving the grades of students? I relied on the public library for computer/Internet access and of course reading for most of my childhood and never had that expectation... no doubt it helped me indirectly because I read a lot and I had no consistent access to the Internet otherwise, but how do you define "effectiveness/reach"? Can a filthy library occupied by homeless people be effective? My thoughts: it's largely up to parents to bring their kids to public libraries and encourage them to read. And that's not going to happen if it's not a comfortable place to spend time (i.e. clean and quiet). What's in the collection is of secondary importance.
