OER 101

Knowing Where to Find OER

Learning Objectives

By the end of this lesson, you will be able to:

  • List useful repositories and search tools for finding OER


Locating useful OER is both critical for OER adoptions and is a common stumbling block when first engaging with OER.  Some barriers to OER adoption are related to discovering and selecting appropriate OER. This lesson will help you take a look at a variety of locations and methods for finding OER.

Knowing What to Look For

Perhaps the most important first step when searching for OER is knowing what you are looking for. Are you seeking OER video lectures that discuss Microeconomics? Or are you looking for a full 100-level OER course on Psychology? If you are able to narrow down your search to a particular field of study and have an idea of the types of OER content you are seeking, your searching will be much easier. The syllabus for a course is often a great place to see what content is already being used.

OER Repositories

Institutional Repositories (IR)

Like many higher education institutions, Lansing Community College has a system-level OER repository meant to store OER created and adapted by LCC faculty and staff. Repositories like this have OER organized into collections and communities, usually following a subject-focused organizational structure, or one that represents OER from the different colleges and departments within the institution. IRs like this can be very useful in terms of finding OER that have been curated by librarians and educational staff. Full downloads of OER content are typically hosted here.

A more complete list of repositories, referatories, textbook collections, and curated lists by subject can be found on the LCC Library’s website Research Guide: Open Educational Resources

Examples of Institutional Repositories for OER:

Open Repositories

Open repositories provide free hosting for OER content, and typically offer services that make it easy to find and curate OER on their platform. These repositories may or may not be associated with educational institutions, and OER content from all over the world can be found in them. Full downloads of OER content are typically hosted here, as well.

Examples of Open Repositories:


Referatories are websites that curate reviews and collections of OER, but send visitors to other website to access the full, downloadable content and files. In some cases, Open Repositories can also act as referatories, storing some OER content collections, and referring visitors to other websites for some OER downloads.

Examples of Referatories for OER:

Search Tools

Google Advanced Search

Google’s Advanced Search allows you to filter results by usage rights, but they do not offer a list of licenses to search by. Instead, they give their own descriptions of the licenses:

  • not filtered by license (default)
  • free to use or share (CC BY-NC-ND)
  • free to use or share, even commercially (CC BY-ND)
  • free to use, share, or modify (CC BY-NC or CC BY-NC-SA)
  • free to use, share, or modify, even commercially (CC BY or CC BY-SA)

To find content that you can modify, select one of the two last options in the dropdown menu.

Google Advanced Search “usage rights” filter

CC Search

Creative Commons has its own search tool called CC Search, which makes it easy to activate filters for CC-licensed content on multiple search tools and platforms at once.


These search tools rely on license metadata being detected on the source webpage(s), but it is wise to confirm the CC license on the content you want to reuse before doing so.

Apply Your Knowledge

Now that we have a basic understanding of what OER are and where or how we might find them, let’s put this knowledge to practice. Before you begin, select both a specific area of learning or research (eg Geography, Biology, Economics, etc) and a type of content you wish to find. The OER artifact (content) you are seeking can be as small as a single image or as large as an entire course.
