Another week with double-digit gains in all but one category led to a 15.1% jump in unit sales of print books from the comparable period in 2019 at outlets that report to NPD BookScan. The juvenile nonfiction segment had the biggest gain over the week ended Aug. 3, 2019, with units spiking 40%. The usual suspects were atop the category bestseller list in the week—Big Preschool Workbook was #1, selling nearly 33,000 copies, followed by Crystal Radke’s My First Learn-to-Write Workbook, which sold more than 28,000 copies.

Trump’s Too Much and Never Enough had another big week, selling more than 154,000 copies. Two backlist titles had strong weeks: On Tyranny by Timothy Snyder sold more than 36,000 copies, putting it at #2 on the category list, while SuperLife by Darin Olien was in fourth place, selling more than 23,000 copies. Three new Disney-related books published by Simon & Schuster’s Igloo Books imprint helped to drive an 11% increase in the juvenile fiction category. Disney Princess: Enchanted Pop-Ups was #1 in the category, selling more than 22,000 copies. Disney Pixar: Awesome Pop-Ups and Marvel Super Hero Adventures: Super Hero Pop-Ups each sold slightly more than 11,000 copies, placing them in the fifth and sixth spots, respectively, on the category list.
