Open Educational Resources at the University of Bonn
These web pages provide in-depth information about the learning materials available as open educational resources (OER).
What are "open educational resources"?
Open educational resources (OER) are learning materials that can be used and reused free-of-charge under special licenses such as Creative Commons (CC). This can include individual materials, but also complete courses or books, whilst the classification can be applied to any medium. Course materials, textbooks, images, presentations, streaming videos, multimedia applications, quizzes and podcasts—all these resources are classified as OER, if they have been published under an open license.
Using open licensed materials correctly
Materials with an open license cannot be subject to unrestricted use. CC licenses specify how to quote the work correctly and the uses to which material may be employed. These instructions require compliance: failure to do so represents a breach of copyright.
What do the various CC licenses mean? There are six forms of Creative Commons license; some permit modifications of the material; others enable commercial use of the material they cover, while others allow only use in unmodified form for non-commercial purposes. The web pages of Bielefeld University of Applied Sciences Library provide a short overview of this topic. The official license texts are available on the Creative Commons homepages.
The German-language article OER leichtgemacht mit der TULLU-Regel available on OER.info explains how to use CC-licensed material correctly, what to take into account and what information you are required to submit.
Searching for and finding open-licensed material
Do you need open-licensed learning materials for your studies or out of private interest? We have collected a number of links to sources of OER materials. Please note: many portals provide both open access and copyrighted materials on the same site. We recommend that you check the license conditions of each individual source.

Publishing your own materials with a CC license
Have you developed materials which you would like to make available with a CC license? This raises a number of questions: which CC license best applies to your materials? Where can you publish your materials? What are others allowed to do with your materials? For whom is the material suitable?
The German-language article Welche CC-Lizenz ist die richtige für mich? on OER.info provides information to help you select the most suitable license.
Please address any other questions you might have to the BZH team. We are happy to provide advice on all the issues relating to open educational materials.
