License for Resources

OpenIntro LaTeX, code, and PDFs are released under a Creative Commons BY-SA 3.0 license unless noted in the Exceptions. Any materials reposted online must include a visible link to an appropriate OpenIntro page.

Some files are downloaded in a zip directory and include a Read Me file. Adhering to the guidelines in this file ensures the attribution component of the license is fulfilled. Derivative works should also be clearly licensed under the Creative Commons BY-SA 3.0 license, e.g. by linking to the CC license, so that others may continue to benefit from sharing.

Please note that a derivative work cannot be branded or titled in a way that suggests the derivative work is an OpenIntro product or is endorsed by OpenIntro. For example, printing books using the original title of an OpenIntro textbook, such as "OpenIntro Statistics", is not permitted. If you would like for a derivative work to branded as an OpenIntro resource (e.g. if the derivative is a translation), please contact us.
