How many stories were included in the Brothers Grimm’s fairy-tale collection?

The Brothers Grimm’s famous collection, Kinder- und Hausmärchen (known in English as Grimm’s Fairy Tales), comprises approximately 200 stories.12

First published in two volumes between 1812 and 1815, the collection was revised and enlarged seven times by Jacob and Wilhelm Grimm between 1819 and 1857. While the brothers initially collected these tales from oral sources, a small number were also derived from printed materials. The work is highly regarded as the earliest scientific collection of folktales, serving as a foundational model for the study of folklore worldwide.12
