I’ve been keeping a worksheet this year to track the trends of book sales for the calendar year of 2008. It’s been interesting to see how individual categories of books have sold over the year. The biggest gains have been achieved by ebooks. Even though ebooks haven’t broke into the mainstream, ebook sales are growing expontentially. From January through August, the ebook numbers look like this (in the millions of sales):
^19.9% (3.4 m)
^24.3% ($3.3 m)
These numbers reflect increases from same month sales of a previous year (as opposed to Year to Date sales numbers).
The Children’s/YA Hardcover has been hit hard by the loss of Rowling:
-19.9% ($39 m)
-4.9% ($40.4 m)
That 77.2% decline is for the month of July and represents a decline of 77% in same month sales from 2007. July 2007, of course, saw the release of Harry Potter and the Deathly Hallows
Adult mass market sales (50% of which are represented by romance sales) are troubling:
Adult Mass Market
^0.4% (59.5 m)
^ 4.7% (53.2 m)
-9.6% ($77.2 m)
Except for January and July, Adult Mass Market sales have either showed small increases or losses. The biggest loser in sales has been audiobooks. I’m not really sure I know the reason for that. In July, audiobooks posted a 65.8% (11.0m) decrease in same month sales which was followed up in August by a 6.9% (11.9m) decrease.
The entire worksheet can be seen here. I think I need to reconfigure the worksheet for ease of use and to reflect YTD changes.
