Open Educational Resources (OER) by Subject: Welcome


Welcome to the OER by Subject Research Guide!

This guide is intended to be used as a launch point for investigating Open Educational Resources (OER) in specific subject areas.

Also included here are informational videos and links to tried-and-true resources that support your journey from investigation to implementation of OER materials in your course.

If you are new to the wide world of OER, check out Getting Started with OER for tips, tricks, and best practices.

You might notice that some disciplines are full of resources, while other have a scant few. OERs are constantly being created and published. If you are not finding what you are looking for, check back here soon, or reach out directly to the ZTC Team at We are always happy to assist.

To view classes that are offered as no-cost Zero Textbook Cost (ZTC) and lower-cost Open Educational Resources (OER) classes at Skyline College, visit WebSchedule and select ZTC &/or LTC tagged class sections for your search.
