My community has one of the highest library-use statistics in the state. Probably because of an over-educated, elderly population, and our remote location.
We just built a very expensive addition to our already very-nice library. (Which seemed more focused on more meeting rooms, and more rooms for "technology" - seems the library is a center for people working on their phones, laptops, and pads, due to good Internet connectity, desks, light, power, and heat...)
My mother works as a volunteer at our library. At a recent dinner, some of us were complaining to her that the library's physical book collection is problematic - in particular they'll often not have the entire series of a trilogy (or longer), likely having only the latest book, or one in the middle. She informs me we do a lot of inter-library loans for solving this problem.
She then called me back - inter-library loans cost us about $16 on average. And take 1-2 weeks to be delivered. This charge isn't passed along to the borrower, it comes out of the general operating budget.
I observed that it would be cheaper to Amazon Prime the book directly to the borrower, if for some reason they needed a physical book... (The library already has a sizeable collection of loanable e-books.)
Curious.
