My trouble with Good Reads, the website, is that it depends upon ISBN, and I actually read a LOT of pre-ISBN books that are out of print. I blame this on working near the downtown branch of the Chicago Public Library, which contains a lot of old books.
So I can't enter a bunch of the books I read!
I mean, I don't really think of most of these books as old - since most were published in my lifetime.
I guess I'm half antiquarian,
with just a streak of contrarian.
