"The Blue Fairy Book" by Andrew Lang is a collection of fairy tales published in 1889. This groundbreaking volume launched a revolutionary series that transformed children's literature. Drawing from diverse sources—the Brothers Grimm, Arabian Nights, Norwegian folklore, and French tales—it assembled beloved stories that had never before appeared in English. At a time when fairy tales were dismissed as harmful for young readers, Lang championed their value, sparking a generation-long shift in public perception. The collection features some of the most iconic tales ever told, translated and adapted by Lang and his wife Leonora.
