Some libraries have a large collection of leisure reading. When I worked at Hahnemann, now Drexel, I used to borrow books! I could get things from them right away that I was unable to get for the Free Library system. (Not to imply that I don’t love my library! And it is facing dreadful prospects now with our mayor’s budget cuts!)
For the first time the library where I work is starting a collection based on books staff has brought in. It isn’t cataloged and it won’t be monitored. It is a really unique collection.
It will be interesting to see what happens.
