The reason it has taken as long as it has is that I wanted the look and feel to be as pleasant as possible, while at the same time using the features that make using an e-reader a different experience from reading a book. For example, there are no page numbers and instead there is a linked table of contents.
Because there are no physical pages, I wanted to make it clear where the end of a poem is, rather than have to turn the page to find out if that was the end or not. To this purpose I have put small printer's leaf ornaments at the foot of each poem.
The link above is still to the paperback version, but the Kindle version should be available by 1st March, and when it is I shall change the link if necessary.
I also have a version ready for the Sony Reader and iPad, iPhone and iPod, so my next thing to learn is how to make it available on those machines.
