If your head is still spinning after 2009′s triple digit growth rate, you’ll need a clamp to steady your skull when you read that January 2010 e-book sales posted a nearly 370% jump over the same month in 2009, according to the International Digital Publishing Forum and the Association of American Publishers. The numbers are $31,900,000 for January ’10 compared to $8,800,000 for January ’09. January was also the biggest e-sales month ever, and it wasn’t even close. The biggest month to date was December ’09 at $19,100,000.
