The Strand Book Store is a New York institution, with four floors of books, and 93 years of tradition. But while it survived a Great Depression, World War II, 9/11 and Amazon, it has struggled during the era of COVID-19. New Yorker contributor Kelefa Sanneh talks with the Strand’s owners, and with the owners of EyeSeeMe, an African-American children’s bookstore in St. Louis, about how independent booksellers are finding ways to cope during the coronavirus pandemic, and about the community of readers that wants them to survive.
