I think the needs of grad students and researchers are highly field-dependent. I'm a mathematician, and I still use the library for older books. (Journal papers, even older ones, are mostly on-line now.) But my colleagues in e.g. biology, where things move a lot faster, don't seem to ever set foot in libraries.
