Under the Creative Commons licenses we discussed in the last section, giving attribution is a legal requirement for use. Even if content is in the public domain and there's no legal requirement to give attribution, it's still a best practice to note the source and copyright status because:
. Here are some helpful guidelines for providing attributions:
Time saving tip: I highly recommend using the Washington Open Attribution Builder to automatically generate your attributions in a standardized format!
Remixing content with different licenses
One of the reasons to provide clear attributions (even for public domain materials) is because OER adapters often need to mix materials that are available under different licenses and copyright statuses. You might, for example, use some images that are CC BY-NC and some text that's public domain in your CC BY licensed OER. You can't change the license or copyright status of other people's materials, but you can add a CC Open license to the portion of the work you contribute.
If you create a derivative of (i.e., adapt rather than copy) a work, the license of the original work (if it's ND or SA) may restrict what you can do with the resulting work and how you can license it (see this license compatibility chart from the Creative Commons wiki). The best way to handle this is to keep track of the sources and licenses of the materials you use and talk to a librarian before incorporating sources that have SA or ND licenses.
