I grew up in the middle of nowhere with not much to do except work, play sports, and read. I would have killed for a camera in those days. But my grandmother was a librarian in the state capital 60 miles away and she brought me books by the grocery bag full and I read every one of them. I asked her for every western and science fiction book they had. But those books are long gone. They never were mine.Interesting and ironic that you should mention books and sorting. I just recently started cataloging my books. I have lots. My enduring interests are history, literature and (my first adolescent love) sci-fi. I have cataloged most of the sci-fi (about 450 volumes) and have discovered a first edition of The Man In The High Castle and a first edition of Foundation. Worth a good bit (close to $1k for books I bought for less than $20 total). The neat thing is discovering things that I have not read in many decades. I intend to remedy that.
