I’m impressed, though, that you know the year you bought the book. I’ve never been that well-organized.
Um, yeah, about that. A thing I’ve done since high school is write the date I bought the book (and sometimes the bookstore as well) inside the front cover somewhere. So, with only a handful of exceptions, I can actually tell you the day. But even when I stumble on a book where I somehow forgot to do this, I can generally still recall the purchase date, usually within a month or so. For me, it’s not about being organized, exactly, but about having a peculiar relationship with time.
