It is not currently available in hardcopy. I am interested in comments from people as to whether they would want it to be. The kindle is up at $2.99. If I self-publish a hardcopy with CreateSpace it would be substantially more than that, and if I go with a commercial publisher more still.
I am also interested in comments by people who read it and spot mistakes. One of the advantages of an eBook is that it's easy to make minor changes.
