Kaarle Krohn's Folklore Methodology was the first systematic attempt to state a method of studying folkloristic materials. For centuries scholars had collected folkloristic texts and had commented on them, but they had not tried to formulate a method of investigating folklore.

Folklore Methodology became the handbook for the great Finnish School of folklore research. It provided for its students a guide to the geographical research of traditional materials, a radical departure from the literary scholarship that had dominated folklore studies.
