This may be a big city mentality, but I've noticed that the nature of libraries has been changing for well over a decade. They are changing so much that the book lending part may be becoming less relevant, while the shared access to resources (both literacy and data based) is becoming more significant.

A lot of these resources are also people oriented. You go to libraries to pick the minds of librarians, meet authors, learn with friends (i.e. the provide a space to study). I think that this may be a bit of a push back from the isolating nature of technology. After all, why would you need to leave your home when everything is at your fingertips online? The most obvious answer is to share your time and interests with others.

So maybe the lending part of libraries will become insignificant while their role in learning and spreading literature via other avenues will grow ... meaning that the vulgarities of ebooks will be irrelevant.
