Lizenzierung und Nutzung offener Bildungsmaterialien - Handreichung für Lehrerinnen und Lehrer ( Licensing and Use of Open Educational Materials - Guidance for Teachers)

From Google's English:

"Teaching digital media has brought copyright issues into the daily lives of teachers with new urgency. The fact that Open Educational Resources can provide an answer to these questions is now understood by many teachers. But what about working with free licenses and using open educational materials in practice? The Saarland Ministry of Education and Culture and the State Institute for Education and Media (LPM) have published the guideline "Licensing and Utilization of Open Educational Materials". The guide covers legal issues, the practical application of OER and references in the network."
