Unit sales of print books rose 5% in the week ended Sept. 20, 2015, compared to the similar week last year, at outlets that report to Nielsen BookScan. The adult nonfiction segment had another strong week, with units up 14%. Why Not Me? by Mindy Kaling had a solid debut, landing at #1 on the adult nonfiction bestseller list, with more than 37,000 units sold. Another new book, Trim Healthy Mama Cookbook by Pearl Barrett and Serene Allison, hit the list at #4, selling more than 18,000 copies. A backlist book, Dave Ramsey’s The Total Money Makeover: Classic Edition, sold more than 33,000 copies in the week, putting it at # 2. Unit sales in juvenile nonfiction rose 8% in the week. The top three titles on last week’s juvenile nonfiction list—Secret Garden and Enchanted Forest by Johanna Basford and First 100 Words— stayed put this week, but Chelsea Clinton’s new book, It’s Your World, landed at #4, selling just under 5,000 copies. With no big debuts hitting the list, unit sales inched ahead by less than 1% in the adult fiction segment. The top-selling new book was Memory Man by David Baldacci, which sold more than 17,000 copies and was at #7 on the adult fiction list. A new #1 bestseller in juvenile fiction didn’t stop units in the category from falling 4% in the week. Michael Vey 5: Storm of Lightning by Richard Paul Evans topped the category chart, selling more than 18,000 copies in its first week on sale.
