David Martin is available in paperback and e-book on Barnes & Noble, in paperback on Amazon, in e-book on Kobo, and via a number of distributors. I am now completely published. Next comes finding some way to get people to notice it.
I've downloaded a couple of PDFs discussing ways to advertise your self-published book. We'll see if they have anything to add to what I've already done.
Now I'm beat and have a 9 hour train trip, tomorrow...so I'm wimping out.
