What does one find if one digs a little bit deeper? Not much deeper, just a little?

I went over to Advanced Book Exchange, a/k/a Abebooks website, to see what kind of titles might be out of print and floating about second-hand with Nat Hentoff as the author. Here's a quick list of the titles pertaining only to music, and it will omit some titles at that.
