My memory says that, when I got my BA, at a State U, there wasn't a semester went by that books were more $$ than my tuition. Of course, that wasn't an "ivy league" school, but a solid education nonetheless. So, yeah, books maybe 500, tuition less, so by today's fees, free.
I'll probably step on some toes (what else is new .. ??) .. however, don't even get me started on the amount of money that gets poured into College Sports ..
