When I’m reading archaeologically, I’m not reading for pleasure. I read the way I scratch for an idea, digging down deep so I can get something out of it and use it in my work. I read transactionally: How can I use this? It’s not enough for me to read a book. I have to “own” it. I scribble in the margins. I circle sentences I like and connect them with arrows to other useful sentences. I draw stars and exclamation points on every good page, to the point where the book is almost unreadable. By writing all over the pages, I transform the author’s work into my book—and mine alone.
