Many OER repositories have a peer-review system in place to evaluate OERs. Below are a few examples of what these reviews look like in the repositories.
Open Textbook Library (OTL) includes faculty reviews alongside the open textbooks in the library. OTL uses the same review rubric as BCcampus, inviting faculty members to rate textbooks on the basis of comprehensiveness, content accuracy, relevance/longevity, clarity, consistency, modularity, organization/structure/flow, grammatical errors, and cultural relevance.
MERLOT is a repository of open educational resources that adds new resources via a peer review process. The site has organized more than twenty editorial boards to coordinate peer review activities. In addition, you as an instructor can join the MERLOT community and post your own reviews of the materials on the site.
