The final numbers from Nielsen BookScan are in for 2011 and they show that print sales through the outlets it tracks fell by just over 9% in the year. Total units sold were 651.2 million. The decline in 2011 was about double that of 2010 and reflects the closing of Borders and rise in digital sales. In this week’s issue of PW, we note that adult fiction and mass market paperback had the largest declines in the year.

Print sales in the week after Christmas took a steep dive, down 30% compared to the same week in 2010.
