La Signification culturelle des industries lithiques Book

I read this many years ago in graduate school, and returned to it this week to follow up on a thread in my own research. I don't remember getting anything out of it back then, probably because I was skimming around a thousand pages a week to prepare for comprehensive exams (what a stupid way to prepare future faculty these exams are), but having taught American history for about three times as long as I was a grad student, the insight and power of Appleby's analysis forcefully struck me on this rereading. There's a reason why this is required for every Americanist.
