While I am absolutely in favor of authors getting paid, and paid first, I fail to see why on earth they should get paid again when an used book is sold, no matter what the medium it is in (paper, electrons, little clay tablets,or cold stone slabs). Once it was sold the first time, it is just another commodity. When somebody sells you an apple, or builds you a custom deck, or a fly rod, or a garden fence, or a camper shell, or uncounted other things that they (singularly or plurally) spent their time and energy on, they are not entitled to demand more pay when you sell that thing. How is selling a used book any different? It ain’t. One its sold, it isn’t your anymore. I also think you have a greatly exaggerated view of how long books last in the library. I’d venture they can get many more than 30 reads before replacement. I know my book collection includes a lot of books I’ve read and re-read that many times or more. And the books I used in grad school and for work get even more use without wearing out. I read all the time, have since pre-school, and I have a reading/writing job (Historical archaeologist).
