I was just perusing the Times Higher website when I came across this article:

It reflects a growing concern in libraries (as previously mentioned), balancing the quiet spaces that many users enjoy using with the needs of modern social spaces other users require.
It is interesting to read the opinion of an academic when the majority of libraries focus on student needs for study rather than the academic staff. The content of libraries serves both but the buildings themselves are usually student focussed.
Certainly this is going to be an issue for years to come.
