Yes, I can't speak upon how a library keeps books now but I'm sure that shows publishers want them sold as an e-book. I think publisher's always hated the agreements with libraries but honoured an understanding at one time. Writing and literature while always copywrite and for profit, I think they understood to have an audience they needed the library. Now people think everything free as poor in quality, and they have people where they want, ignoring culture and the value of art, literature can offer.
Everything has been reduced to what a coffee costs at McDonalds, which similarly has mostly angry customers demanding too much without the cost in fabric (culture/people) forgetting actual value.
