Swedish folktales and legends are at times humorous, enjoyable to read. It has come down to us thanks to collecting efforts of such industrious field pioneers as Gunnar Olof Hylten-Cavallius, Gabriel Djurklou, George Stephens, Per Arvid Säve, and many others. Many Swedish fairy tales and legends were put down in writing between mellom 1837 og 1850 by Gunnar Olof Hyltén-Cavallius. He left a large collection of folktales and legends from the mid-1800s, Svenska Folk-Sagor, Legender och Äfventyr (Swedish Folktales, Legends, and Fairy Tales)., and added to his collection until 1882. In his collection there are recordings by men and women, ministers, nobles, farmers, servants, and so on. In the early half of the 1900s the Kungliga Gustav Adolfs Akademien (a Royal Academy) published series of of Swedish fairy tales and legends of uneven quality, as well as fragments.
