Be sure to check out our Open Course Resource Center for information on how to reuse and adapt our materials for a variety of uses.
All of our course outlines -- that is, the courses with all the learning materials subtracted -- can be reused by anyone, anywhere, under the CC BY license (see below).
We do not own most of the learning materials that we use in our courses, but we try to use open materials wherever possible.
Below is an explanation of the various licensing you may encounter throughout our courses. Although we strive for accuracy, you should verify copyright and licensing for yourself before reusing any materials.
