I annotate aggressively. If I’m reading a piece of really long fiction, I often find that there are these fabulous things I want to remember. I want to take notes on it, so I highlight it, and if I have a thought about it, I’ll type it out quickly. Then I dump all these clippings into a format that I can look at later. In the case of War and Peace, I actually had 16,000 words worth of notes and clippings at the end of it. So I printed it out as a print-on-demand book. In short, I have a physical copy of all of my favorite parts of War and Peace that I can flip through, with my notes, but I don’t actually own a physical copy of War and Peace. Clive Thompson.
