Do you use a tasseled kind of bookmark you'd get at a bookstore (with inspirational, library-based phrases on one side and the bold font address of the bookstore that sold it to you, on the other)? The ribbon that is stitched into the spine of the leather-bound books? I use a post-it note and write down words that I don't know or phrases that I wish to remember. This is one of the greatest things about the Kindle app, on my phone!!! Touch the word and it looks it up, instantly. When I go back to reading paper books, I will instinctively reach to touch the page, when I come across a word that is new. Douglas Preston and Lincoln Child use a LOT of words I have never seen before and cannot work out via any of the very few languages I happen to be able to read Also lists of things I need to do, after work, go on the post-it. It is fun to re-read a book and find my old bookmark. I can tell when I read the book last by what was on the bookmark. "Buy fireworks at reservation" -must have been just before the 4th. "Fix headlight" -just after I got pulled over "Shovel driveway" "Mortgage" "Weed garden" Used to be (and I still do it if I lose my bookmark) I'd just look at the page number and use a mnemonic to remember it but that's much slower than a bookmark and I have to actually use my brain which, if I'm at work, I try never to do. "We don't pay you to think." "Sweet. I'm'a stop doin' it." What a relief that moment was. What's your bookmark?
