NPD BookScan became Circana Books in March, following the merge of NPD Group and Information Resources, Inc. (IRI) in 2022.
Some publishers classify titles that are primarily text, or art books, as graphic novels; ICv2 removes those titles from the rankings.
Circana BookScan covers approximately 85% of the U.S. trade print book market.
The company collects weekly point-of-sale data on print books from over 16,000 locations including e-tailers, chains, mass merchandisers, independent bookstores, and more.
