I personally own a lot of books. Within the professons, I think it's safe to say medicine is known for having a lot of books; within medicine, pathologists are known for having a lot of books; among the pathology residents, I'm known for having a lot of books.
Much like the rug seller becomes a collector of the best rugs, we are becoming keepers of an insane library. I anticipate our special collections will eventually beat the local public library's.
The point is: people are consuming a huge number of books. And shedding some of them. Just the number they shed is overwhelming.
The house behind us is up for sale. I wonder if I should approach the buyers (some investors) about converting it to a book cafe?
My FIL is a director of a public library system. Weeds tons of books.
I remember more than ten years ago, driving with my father for 40 minutes at 2:00 AM to go to a 24/7 bookstore that had a great coffee. We would do that often, specially in the odd hours where it was not as crowded and the experience much more enjoyable. I started reading "Dune" and "Tao Te King" in there while drinking tea of coffee and talking to random people I never met again. Now, that place is a clothes store, there is no nice bookstores in my city anymore. I don't believe that reading on a kindle or similar device on a coffee shop will have the same effect but then, it might just all be nostalgia...
