Kindle Books from March 2009 to May 2010

Kindle Book Count 2009-2010It has been 14 months since I monitor Kindle book store size on a daily basis. I started it in April 2009. Back then Kindle software 2.0.2 was just released, Amazon was being sued by Discovery Communications and Amazon itself was sending DMCA takedown notes to, Fujitsu FLEPia was expected to take eReader market by storm with it’s color eInk and first rumors about what would become 9.7″ Kindle DX surfaced. Kindle Book Store just broke 250,000 book margin back then…

Now there are 510,000+ books in Kindle Store and counting. I used to publish Kindle book numbers on a monthly basis but then I got lazy. It is time to fix this and publish all 14 months worth of data at once!

As you can see, the book count was increasing in more or less linear fashion. There may be some seasonality or irregularities to it. Hard to say since one year is clearly not enough to spot seasonal trends (if they exist in publishing industry).
