It’s a book I’ve already read, so I went to kindle.amazon.com to see if I had made any annotations. Turns out it’s one I’ve got multiple copies of (it was a freebie in all the major e-book stores for a while), so my markup’s on some other version. (If I’ve actually read an e-book, there is always markup; this is one of the biggest changes e-books have made to my reading habits.) I wrote back and said, “Yes.”
