In late 2009, Open.Michigan joined forces with the Creative Commons (CC) to gather information on how copyright law plays a role in, and perhaps acts as a barrier to, the production of Open Educational Resources (OER). CC and Open.Michigan conducted an exploratory survey of issues associated with incorporating materials released under varied license terms into a single open resource. The survey results showed that OER creators feel incorporating third-party content is important to their ability to create high quality materials. It also revealed that OER producers encounter copyright issues when creating their materials, and most commonly rely on exceptions and limitations to copyright when including third-party content in the OER they produce. The complete survey results are detailed in this paper, “Evaluating the Understandings, Uses, and Management of Third-Party Content in OER.” This paper is available on the CC website along with the original survey questions and other supporting documents.
