(OER) Faculty Guide on Open Educational Resources: Where to find OER

Learn to create OER

Finding the right content for an Open Educational Resource (OER) can be the most challenging part of using and creating OERs. The resources listed on this page can help you find OER in your subject area which you can choose to adopt completely or mix, match, and customize to create a customized resource for your students.

OASIS - OER Search Engine

Advanced Search

Openly Available Sources Integrated Search (OASIS) is a search tool that aims to make the discovery of open content easier. OASIS currently searches open content from 71 different sources and contains 164,857 records. OASIS is being developed at SUNY Geneseo's Milne Library in consultation with Alexis Clifton, SUNY OER Services Executive Director.

Mason OER Metafinder OER Search Engine

George Mason University logo

The Mason OER Metafinder (MOM) performs a simultaneous search across 18 different sources of open educational materials. Because it is a real-time, federated search, it can take a bit longer than searches of pre-indexed, curated content; however, as compensation the results returned are absolutely up-to-the-minute for each search target. Additional results will continue to trickle in as the search continues running and you begin examining your results.

OER Repositories

OER repositories contain more than just open textbooks.  All content featured within these pages is free but usage rights vary. Materials in these repositories are released under a Creative Commons license while some are in the public domain.

Open Textbook Collections

Open Textbooks

Open textbooks are free, online learning materials with Creative Commons licenses. Many of the collections will have links to the same books, but each will have a particular focus, and items you can't find in other collections.

Federal Government Resources for OER

Everything published by the Federal government is free of any copyright restrictions.  The research, reports and websites can be useful resources for classes when creating your own course material.

Try to search a specific agency's website.  A-Z List of Federal Agencies. Many times these materials are not retrieved with simple Google searches.   Here are some examples of US Federal Databases. 



Public Domain vs. Creative Commons

What is the "Public domain"? 

A work of authorship is in the “public domain” if it is no longer under copyright protection or if it failed to meet the requirements for copyright protection. Works in the public domain may be used freely without the permission of the former copyright owner. For more information on what constitutes Public Domain see

What is Creative Commons ?

"Creative Commons is a global nonprofit organization that enables sharing and reuse of creativity and knowledge through the provision of free legal tools. Its legal tools help those who want to encourage reuse of their works by offering them for use under generous, standardized terms; those who want to make creative uses of works; and those who want to benefit from this symbiosis. Its vision is to help others realize the full potential of the internet. CC has affiliates all over the world who help ensure our licenses work internationally and who raise awareness of our work."
