LibGuides: Open Educational Resources: Finding OER

Open Image & Media Collections

Need images and other media to include in your own OER, presentations, publications, and more? Search the repositories below for access to millions of objects that can be used freely with proper attribution.

OER Repositories

In these repositories, you can find OER created by others and ready for your use or adaptation, including textbooks, lesson plans, syllabi, videos, images, and more. Browse these repositories by subject or search for materials using relevant keywords.

Repository	Pros	Cons
OER Commons	One of the largest OER repositories Covers multiple disciplines Allows for sorting by education level, reuse options, and by standard	Rating system is a bit unclear
OERTX	New OER repository from the Texas Higher Education Coordinating Board Covers multiple disciplines Allows for sorting by education level, reuse options, and by standard	Covers most of the same resources as OER Commons since the platform is shared Rating system is a bit unclear
OpenStax	High quality textbooks for introductory level college courses	Little content for upper level courses Not much coverage in the humanities
Open Textbook Library	Large collection of textbooks with published peer reviews by professors Includes some upper level/graduate textbooks Easy to use interface	As the name suggests, the content is limited to textbooks
MERLOT II	Lots of filtering and limiting options when searching Wide range of disciplines represented Wide variety of material types	Search interface is a bit clunky
OASIS	Searches content from over 60 different sources, you can sort by license type and type of resource.	Can't sort by education level
OER Metafinder	Simultaneously searches multiple repositories, could give you good ideas of other repositories to look in	Search interface is difficult to use Search results sometimes take you to the main page of different repository and then you have to redo your search Not easy to determine licenses for items

Looking for supplemental materials?

If you're interested in finding open materials that might be relevant to a text you're teaching, try using MERLOT II's ISBN search function. Just input the ISBN of the text you're currently using to see what materials could be supplemental.

How can the Libraries help?

Librarians can help you find OER suited to your course needs. We'll consult with you to understand your learning objectives, current course materials, and student needs to inform our search together.

Discipline-Specific OER

Many other libraries have curated lists and guides to existing discipline-specific OER. We invite you to review those below -- or, better yet, just ask us for help finding what you need! Librarians can compile guides to OER customized to your course.
