To locate materials in OER Commons you can search or browse. There are two ways to search and four ways to browse.
Searching
You can do a simple keyword search using the search box located in the upper right corner of every page.
The second way to search is to use the advanced search, which provides a wide variety of options for refining your search. In the “Find results by Keyword” box, search for an item using a keyword and refine your search using any combination of over 70 filtering criteria.
Searches can be saved by clicking the “Save This Search” button located on every search results page. Saved searches are placed in your portfolio. We’ll be talking more about your OER Portfolio in another module.
Too many results?
If you want to narrow the number of items listed on your search results page, you can filter the results. Using one or more of the 70 filtering criteria, you can narrow your search to find exactly what you are looking for. The “Filter Results” button is located on every search results page.

Browsing by Course-Related Materials or Libraries and Collections: located in OER Teaching and Learning Materials. You can also browse by subject areas as well as grade level.
Under the heading “Course-Related Materials,” there are three categories:
- Full Course—to see all or part of a course
- Learning Modules—to see a portion of a course
- OpenCourseWare—to see all materials in MIT’s OCW Consortium.
At a glance, you can see how many items are in each category. The number in parentheses shows the quantity of OER items for that category. If, for example, you don’t have time to browse hundreds or thousands of OER items, filter your search after you click on the category.
If you are looking for a specific instructional component such as a simulation or a video lecture, course-related materials are also categorized by 16 different instructional components. Clicking on any one of these components will display a listing of all the items for that particular instructional component.
Under the heading “Libraries and Collections,” you will find digitized primary sources from a wide variety of digital media collections and libraries.
You can also browse each individual content provider’s collection for either the Course-Related Materials or the Libraries and Collections.
