According to a report from the Association of American Publishers, book sales have fallen in April a slight amount (3.5%) to $272.7 million. Year to date sales are flat at $2.183 billion. I’ve decided to start keeping a spreadsheet although I’m not certain how it will look in final form (suggestions from accounting folks welcome).
The usual suspects are seeing increases such as eBooks and Adult trades. The most fluctuating market in 2008 seems to be the Children’s Hardcover. I’m not sure whether you can blame that on a lack of a Rowling book or not. Adult hardcovers are taking a pounding, falling for the third month in a row. Via ShelfAwareness
