I walked out of the library today and was treated by the free books stand. I got Crime and Punishment, The Crucible, The Old Man and the Sea, and 4 others of equal caliber. And when I got home, I was reminded I'm out of shelf space. In mymind, that's a great reason to get a bookshelf. To my wife, not so much. Dead tree books have negative value to a growing percentage of the population.
BTW, for those buying, unless you're a reporter, I highly recommend the large size. If you look at the notebooks of great men, most tend to be closer to the larger size. Michelson is the one that sticks in my mind, since I walked past those notebooks every day for 7 years.
