These days, I do nearly all my reading on an e-reader, currently an InkBook Obsidian, but I do on occasion return to the dead tree books of yore. Typically this will be because someone gave or loaned me said dead tree edition. Such was the case with Dune, which, being a door-stopper of a book, I eventually bought in e-form so I wouldn’t have to fight with it when reading at lunch; and such is the case with the Nero Wolfe books, which my father sent to me in a box a while back. I’ve read them all before, but now I’m reading them again, because who doesn’t like to spend some time visiting old friends? The one I’m currently into is Plot it Yourself, in which Wolfe goes up against a con artist with a fondness for pretending that popular novels are plagiarisms of his or her own work, and also for knives.
So I have way more books on my e-reader than I can keep track of these days, thanks mostly to BookBub, which means that after I finish one book I have to decide which one to read next. I could do something normal like have them in a first-in-first-out queue, but that would be too easy. So instead I use Calibre to help me pick a new book after I finish one. Because I’m random that way.
