Evaluating Open Materials

Peer Review

Many OER are produced through a process affiliated with a higher ed institution. And, many institutions use a review process for both editorial/copy editing review and peer review before releasing the resource to the public.


OpenStax textbook projects are developed and peer-reviewed by educators to ensure they are readable and accurate, meet the scope and sequence requirements of each course, are supported by instructor ancillaries, and are available with the latest technology-based learning tools. You can learn more about the production process for OpenStax titles in the post How OpenStax Books Are Made.

Open Textbook Library:

This is a collection of open textbooks and many of them include reviews by faculty. These open textbooks can be downloaded for no cost, or printed at low cost. In order to be added to this site, the textbook must be either used at multiple higher education institutions; or affiliated with an institution, scholarly society, or professional organization. The library includes hundreds of textbooks, with more being added all the time. Around 60% of books in the Open Textbook Library have been reviewed. In addition, most open textbooks are reviewed during production, using systems implemented by the authors and publishers. Since new books are being added all the time, not all books have reviews. But, new reviews are also being continually added. 


This LOUIS OER Commons site is relatively new but the site has the capacity for user reviews of a couple types.

Users can apply star rankings, complete an embedded rubric review to give a numerical score across some areas, add comments, or submit a review as a standalone resource. 

We also try to expose the reviews of other sites through the LOUIS OER Commons site. For example, for titles available within the Open Textbook Library, we provide a link to their site so users can review the faculty reviews there:
