RELX Remains World’s Biggest Book Publisher: “The turmoil caused by the global pandemic was not enough to unseat the RELX Group as the world’s largest book publisher in 2021. Though sales fell 3% from 2020, the STM and legal publisher still held a healthy lead over second-place Thomson Reuters on the Publishers Weekly annual global ranking. For the most part, the subject areas that RELX specializes in held up well in 2021.” via Publishers Weekly
