Open Educational Resources (OER)

   William & Flora Hewlett Foundation

Open educational resources (OER) are freely accessible, openly licensed text, media, and other digital assets that are useful for teaching, learning, and assessing as well as for research purposes.

Open Education " the simple and powerful idea that the world’s knowledge is a public good and that technology in general and the Web in particular provide an extraordinary opportunity for everyone to share, use, and reuse knowledge."
The William and Flora Hewlett Foundation

What is OER?

"Open Educational Resources (OER) are teaching and learning materials that you may freely use and reuse at no cost, and without needing to ask permission. Unlike copyrighted resources, OER have been authored or created by an individual or organization that chooses to retain few, if any, ownership rights." 

The Open Education movement is built around the 5Rs of Open

  • Retain – the right to make, own, and control copies of the content
  • Reuse – the right to use the content in a wide range of ways (e.g., in a class, in a study group, on a website, in a video)
  • Revise – the right to adapt, adjust, modify, or alter the content itself (e.g., translate the content into another language)
  • Remix – the right to combine the original or revised content with other open content to create something new (e.g., incorporate the content into a mashup)
  • Redistribute – the right to share copies of the original content, your revisions, or your remixes with others (e.g., give a copy of the content to a friend)

Suggested Open Educational Resource (OER) for the Indiana Core Transfer Library


A 2023 collaboration between the Academic Libraries of Indiana's Affordable Learning Committee and the Private Academic Library Network of Indiana's PALSave Team mapped the current courses listed in the Indiana Core Transfer Library to appropriate OER. A searchable table of their map of course to suggested OER can be found here.

The Indiana Core Transfer Library is a comprehensive, continually updated list of courses that are pre-approved for transfer between all Indiana public colleges and university campuses and five independent colleges and universities (assuming adequate grades were earned). 




TOP Open Educational Resources (OER)


ASEE ELD Open Textbooks for Engineering -  This listing of open textbooks is organized by engineering discipline and, in some cases, by subdiscipline.  The resource is expected to be updated by the American Society for Engineering Education's Engineering Libraries Division multiple times per year.

BCcampus OpenEd - Engineering - Open textbooks on many subjects, including biological / physical sciences, computer science, engineering,  humanities, and math / statistics.

Book Boon - Free textbooks written by professors from the world’s top universities, covering topics from Engineering and IT to Economics and Business. 

Directory of Open Access Books - The primary aim of DOAB is to increase discoverability of Open Access books. Academic publishers are invited to provide metadata of their Open Access books to DOAB. Metadata will be harvestable in order to maximize dissemination, visibility and impact. 

LibreTexts - From the University of California, Davis, OERs from multiple institutions on biology, business, chemistry, engineering, espanol, geosciences, mathematics, medicine, physics, social sciences, and statistics.

Mason OER Metafinder (MOM) - From George Mason University, simultaneously searches across 20+ different sources of open educational materials.

MDPI Books - Open access books across all disciplines and enables free and unlimited access to the full-text of all scholarly content published. Additionally, print copies are available for purchase.
