It would make sense to me, at least with textbooks, that it also helps the cream rise to the top (outside of mandated ones for college classes). You can sample several, find the one you like the most, then buy a nice copy of it to keep. I've done that with several books, checking them out from a uni library or finding them by other means and then buying once I decided it was good and I was going to stick with it. I feel like others do as well, others who would never buy them otherwise. Also, if people can sample textbooks, you can easily start to see which ones are the best (subjective, in a way) and they can rise to the top.
