Nils Holgerssons underbara resa genom Sverige is a book by Selma Lagerlöf.
"In 1902 the author received a commission from the National Teachers' Association to write a reader for the public schools.
"She devoted three years to Nature study and to familiarizing herself with animal and bird life. She has sought out hitherto unpublished folklore and legends of the different provinces. These she has ingeniously woven into her story." (From translator Velma Swanston Howard's introduction.)
