Funny you should ask. The short answer is not yet.
The longer answer is that there is a new concept out in the publishing world called "on-demand" hard copy publishing.
Essentially there are now several publishers out there who will make short runs (as little as one book) of hard copy paperbacks which are then mail-ordered out. Amazon offers such a service.
The down side is that it drives up the cost of the book. (My $4.00 books would be closer to $9-10) and I would need to make edits to the books to make them more attractive as hard copies (back cover and spine art, inside cover material, headers with page numbers etc). None of those are very hard but do need some attention and time and I have already decided that I will do so, sometime within the next year.
Since finishing the last book I have been doing some beta-testing on a new version of a timelining program which I am using to outline two new books I'm working on and when I find a natural break in the "creative" flow I will turn my attention to this.
Thanks for the interest.
