Open Educational Resources: Discipline Specific OER

This site is designed to introduce OER initiatives, explain creative commons licensing and OER, and to help you get started searching for Open Educational Resources for teaching and learning.

Open Content


Below you will find the largest, most popular repositories of open educational resources.  At the left you will find links to subject-dedicated pages featuring textbooks, supplemental materials, and video lectures.  Each resource is introduced by a short paragraph that lists what one can expect to find in that particular resource, its developers and their university affiliations in addition to the usage terms associated with the content.  All of the content featured within these pages is free to use, but usage rights vary.  Most content found within these pages is released under a Creative Commons license.  Some content is in the public domain and fewer still are under full copyright but can be linked to or used free of charge.  More information about Creative Commons licensing can be found at the Libraries' Creative Commons guide.


This collection is intended to showcase the potential of open educational resources to curb high textbook prices.  It is our hope that its users feel free to adopt these resources or leave constructive comments about the resources found on these pages.  Comments from students and faculty alike will be thoughtfully considered and used to guide the future development of this collection. If you need additional content, or are not finding what you need in the provided links, please contact Jen Waller, Cody Taylor, or your liaison librarian for additional help with open resources.  

General Open Educational Resource Repositories:

OER Commons

OER Commons was developed to serve educators in discovering, creating, and collaborating around the use, evaluation, and improvement of open educational resources.  Not only can OER Commons help during the hunt for OER, but it can also serve as a place to create resources.  The OER Commons open author tool allows users to combine text, images, audio, and video files into their own customized resource as well as create brand new resources from scratch. Recommended by OU Librarians for the Business, Education, History, Life Sciences, Psychology and Sociology subject areas. 


OpenStax CNX (formerly Connexions)

Connexions is an educational content repository and a content management system that can be used to search for and remix learning modules.  The modular nature of Connexions makes remixing or downloading specific pieces of content a seamless task.  Because content can be submitted by anyone, Connexions features what it calls lenses which provide a mechanism for viewing vetted and endorsed contents. Lenses act as a preliminary quality control measure.  This site is not recommended by OU Librarians for any specific subject areas, although it is recommended for the OpenStax Textbooks. 


Merlot is a web-based repository of educational material that is free, open, and peer reviewed.  Merlot makes searching for resources easy, as it provides a link to the original content, a description of it, and all associated information such as its intended audience as well as its usage permissions. Merlot also features tools for combining content found within its repository. Recommended by OU Librarians for the Business, Education, Music, Political Science and Sociology subject areas. 


Saylor is a modular repository of open educational resources.  Faculty at Saylor compile open educational material from across the web into courses that are modeled after those taught in universities.  Saylor's search feature is a quick way to highlight resources that contain a specific topic.  Recommended by OU Librarians for the Art History, Business, Engineering, History, Political Science and Psychology subject areas.
