Anecdote: waiting for my childs parent-teacher interview in the library of a mid-range highschool in a large city, I casually asked the row of student facilitators how much they used the (pretty substantial) library. They all said, with emphasis, that they'd never used the library once, not even for a single book. Overhearing this a teacher looked at me and shook his head with resignation.
Did you ask them how much they read as ebooks? Libby is very popular.
