Finding appropriate OER can be a challenge. There isn't a single catalog or index from which to search for OER, and those that are available have varying coverage and search features. The time it takes to search for possible OER candidates is often cited as an obstacle by faculty who would otherwise be interested in adopting OER. However, you can get help from your subject librarian! Contact the subject librarian for your department or college with your syllabus and any other relevant information (any texts you hope to replace, what material the OER should cover) and they will try to provide some initial OER candidates for you to review.
Here are some of the more popular places to look for OER, with short descriptions of their coverage, search features, and peer review or ratings.
