The Brothers Grimm collected the stories by traveling around Germany and listening to people. They were interested in the oral traditions of the common folk. They would visit villages and small towns, and sit with the locals to hear their tales.

This way, they managed to compile a large collection of real folk stories that became known as the Brothers Grimm stories.
