Number-crunching - sales figures - Jules

Number-crunching time, as US tax deadline approaches. I thought it might be useful to post sales figures for my books. The numbers here are the total sales from when the book first went on sale to the end of the calendar year cited. Which means you can get the per year figures for 2009 and 2010 with a bit of subtracting, if you're so inclined.

Black Leather Rose	774	922	995
Buildup 1: Mindscan	1304	1466	1554
Buildup 2: Pulling Strings	711	857	918

Other items of interest -- sales direct from the publisher's website have dropped to a trickle, which is not surprising as all of these books have been out for at least two years - the last release I had was in August 2008, before The Day Job Ate My Brain. But over the last 18 months I keep seeing new sales coming in as they add titles to reseller's lists. The really interesting one is that Dolphin Dreams is doing well on Amazon, and having had three months' figures now (Jan-March), it has gone up each month. I'll be interested to see if that's a fluke, or if it reflects increasing Kindle ownership.
