.OER for You and your Students: What is OER?

Defining the "Open" in Open Content and Open Educational Resources:

The terms "open content" and "open educational resources" describe any copyrightable work (traditionally excluding software, which is described by other terms like "open source") that is licensed in a manner that provides users with free and perpetual permission to engage in the 5R activities:

1. Retain - the right to make, own, and control copies of the content (e.g., download, duplicate, store, and manage)
2. Reuse - the right to use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)
3. Revise - the right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language)
4. Remix - the right to combine the original or revised content with other material to create something new (e.g., incorporate the content into a mashup)
5. Redistribute - the right to share copies of the original content, your revisions, or your remixes with others (e.g., give a copy of the content to a friend)

Open textbooks are textbooks that have been funded, published, and licensed to be freely used, adapted, and distributed. - Open Textbook Library

Like traditional textbooks, open textbooks are written by experts in the field and undergo a process of peer review and professional editing and development. Unlike the traditional publishing model, publishers and authors of open textbooks are paid for their labor upfront by the funding organization or grant, instead of relying on sales to pay back their investments.
