Which works may only be made available by teachers and researchers to a limited extent?

Teachers may make up to 15% of a published work available, such as a printed or electronic book, as long as they cite the source and author.

• Reproduction: making copies, for example.
• Distribution: handing out copies, for example.
• Making it available to the public by providing access via an e-learning system, for example.
• Public reproduction in any other way, such as the use of a work in a PowerPoint presentation.

Researchers (including students) may reproduce, distribute, and publicly share a work for noncommercial scientific research purposes (for example, for students) in an amount not exceeding 15%. This provision applies to a specific group of people (such as a seminar or lecture group) for their own scientific research, as well as to individual third parties, provided that it serves to review the quality of scientific research.
All pages consisting predominantly of text are counted for up to 15%; there is no page limit.

This provision is only permitted for a limited group of people, including teachers and participants of the respective event, as well as teachers, examiners, and individual third parties conducting their own scientific research at the same educational institution. Concrete and state-of-the-art effective precautions must be taken to ensure this.
