Just to put in one note - I know I am in an unusual situation here, though - my Irish work sells way better in paperback than ebook. Of course, that's partly that I have a lovely sales outlet in having my own bookshop and people like the idea of meeting the author. But it's also because they're Irish sf works and, so, the reach online is limited. Whereas in Ireland, at events, or chatting to people, they love the idea of the books and so buy them. So, yeah, in total, for instance, Inish Carraig has sold more online, but I've sold hundreds of paper copies (I've never done a count, actually, but it must be coming up near 4 figures now) and they continue to sell better at the moment. Barring the film being made, I suspect that will continue to be the case. (Mind you, my sales are hardly outstanding)
