The William and Flora Hewlett Foundation provides the following definition of open educational resources (OER):
OER are teaching, learning, and research resources that reside in the public domain or have been released under an intellectual property license that permits their free use and re-purposing by others. Open educational resources include full courses, course materials, modules, textbooks, streaming videos, tests, software, and any other tools, materials, or techniques used to support access to knowledge.
Open textbooks, are a particular kind of OER that can help alleviate the burden of textbook costs for students and provide faculty with content that can be customized for their course.
