Scientists have found 27 lost volumes of the Brothers Grimm

In the library of Adam Mickiewicz University in Poznań, Poland, 27 original volumes of the Brothers Grimm's works have been discovered. Scientists believe that these books could shed light on how the authors selected themes for their famous fairy tales.

As reported by the Daily Mail, the found books contain handwritten notes by Jacob and Wilhelm Grimm. Presumably, the 27 volumes found in the library were part of the personal collection of the writer brothers.

The discovery was made by scientists from Adam Mickiewicz University in Poland, who spent six months analyzing each book in hopes of finding a series that was believed to have been destroyed during World War II.

The Brothers Grimm are famous for their fairy tales such as "Hansel and Gretel" and "Rumpelstiltskin." Most of their lives, the renowned writers dedicated to the study of German philology.

Researchers believe that the Grimm brothers' library once contained more than 8,000 editions. Much of the library is considered lost during the years of World War II.
