A Question About Different Book Markets
Here's something curious. Below is my iBookstore downloads for the last 3 days and there is one major market missing from these figures – the UK.
I wonder what experience other authors have had with different geographical markets. I would have expect the US to be the major player but I would also have expected the UK to be well represented; it is, after all, the home of the language we write in.
