These are scans from a book called The Problem of the Media, by Robert McChesney, published 2004. I tried Identifont to no avail. It seems very familiar but I can't put my finger on it. I don't know if it has small caps, but they aren't used in the book. OsFs are, but they are a little darker than the rest of the text, which I thought was strange. Anyway, here goes...
It isn't as noticeable on screen, but in the actual physical book the figures appear much darker than everything else, almost as if it's a bold weight. My wife is trying to go to sleep and is not well pleased with my noise-making, so good night.
