Not that my books are really available at the moment (well, that's not quite true ... I was shocked to find that many of my poetry collections show up through both Amazon's new/used vendors and through the AbeBooks service), but I make the cut due to being on Amazon and in the Library of Congress database.
Of course, the "motherlode" of my poetry is still off at the Poetry Site ... maybe this will be the impetus I need to get back to working on that (which has lain fallow since 2002).
