Unit sales of print books rose 2.3% in the week ended May 22, 2021, over the comparable week in 2020, at outlets that report to NPD BookScan. The relatively small increase is due in part to last year’s release at this time of The Ballad of Songbirds and Snakes by Suzanne Collins, which sold more than 271,000 copies in its first week. As a result of Ballad’s blockbuster performance last year, units in the week dropped 24.4% in the young adult fiction category. The juvenile nonfiction category had its worst week so far this year, with units falling 21.3% compared to the week ended May 23, 2020, when parents were still heavily buying books to teach their children at home. My First Learn-to-Write Workbook by Crystal Radke was #1 in the category last year at this time, selling more than 20,000 copies, and it was tops again in the most recent week, selling just over 7,000 copies. Offsetting declines in the YA fiction and juvenile nonfiction categories was another solid increase by the adult fiction category. Unit sales increased 14.9% despite no big new titles. The graphic novel subcategory continued to be the big driver in the segment, with units soaring 210% to more than 664,000 copies sold in the week, up from about 214,000 copies a year ago. Adult nonfiction sales increased 4% in the week as the category had the two bestselling new books: John Green’s The Anthropocene Reviewed: Essays on a Human-Centric Planet sold more than 57,000 copies, and Daniel Howell’s You Will Get Through the Night sold more than 26,000 copies.
