The German state of Bavaria says it's preparing for the expiration in 2015 of the copyright on Adolf Hitler's infamous memoir "Mein Kampf" by supporting the preparation of new editions with critical commentary -- including one for students.

While "Mein Kampf" isn't actually banned in Germany, Bavaria has over the years used its ownership of the copyright to block publication. But it acknowledges it won't be able to once the copyright expires, 70 years after the author's death.

German news agency dapd reported that Bavaria's finance minister, Markus Soeder, said Tuesday a version for students -- financed by the state government -- would contain commentary by experts that would be easy for young people to understand.

He said the aim is to show "what a worldwide catastrophe this dangerous body of thought led to."
