I’m sure there’s a more sophisticated, librarian-like, way to shelve books, but I’ve developed a system that works for me. Not that you could visit and find every book properly shelved, but the idea is this: shelve the books alphabetically by author, adding “new” acquisitions (the “to be read” books) alphabetically. When I pull one out to read, if I haven’t just received one that deserves a priority in the TBR stack, I read, make notes that suggest ways to improve my work, and then send it to the triage unit. If the book deserves keeping, it goes back on the shelf with a red dot sticker on its spine. It’s been read! If it isn’t a keeper, it goes in a bag to take to the library to be re-sold for fifty cents, or whatever donated books are selling for this month. I try not to mix borrowed library books with my shelved keepers!
