Oddly it has been listed under Marketing?!
Interesting business model – their profits come from relevant advertisements placed in the online downloadable book. Authors, we note, get nothing until people start dowloading, then maybe a few coppers if enough download it!
Still a useful exercise in self-discipline for the author!
