Unit sales of print books fell 8.9% in the first quarter, which ended April 2, from the same period in 2021, at outlets that report to NPD BookScan. The decline was expected, as first-quarter sales in 2021 soared 29.2% over the first period in 2020. Unit sales were 183.9 million in the most recent quarter, down from 201.9 million a year ago, but they were still up about 16% over the first quarter of 2020, when sales began to soften due to pandemic-related lockdowns.
