Honors Ebooks (http://www.ebooksbridge.com/) through Master Point Press has been up and running now for a while, and it seems to be working out great. I was able to update and modernize my 2001 canape book into a newer 2010 version, now running on MPP through the Honors Ebooks program.
Ray Lee has been working on another cool venture, as well, which will soon make the canape book, and others, available in hardcopy print. We are not sure what the timeline will be, but "soon" is the key word.
I have also decided, for various reasons, to switch publishers for my previously-announced book describing a two-way strong opening structure (2C and 2D as both strong openings) to MPP and Honors Ebooks. The ebook version will also be released "soon," with a print version following, as well. See prior announcement
The ebook format has a non-obvious upside, namely that in many situations books tend to be available in ebook format before print format, because creating the ebook version is faster than the print version. For the impatient, ebooks has that additional attraction. But, for those who prefer the feel of an actual book in hand, the print versions will be coming, as well.
