My 6 monthly royalty statement came in from OUP for Image to Interpretation today. A cheque enclosed! for the princely sum of £10.23!
... but what is interesting about this is that most of the revenue was my (tiny) cut of the proceeds made from selling access to digital versions of the book. Ten times more ebooks sold than hardbacks in the same period. Admittedly, this is not a sample that you can statistically extrapolate findings about the whole of the book industry from - but its just worth saying that I'm glad I ticked the "can we make this book available in digital form?" box when signing all the paperwork a couple of years ago.
