The worldwide OER movement is rooted in the idea that equitable access to high-quality education is a global imperative.
Open Educational Resources are teaching and learning materials that you may freely use and reuse, without charge. OER often have a Creative Commons or GNU license that state specifically how the material may be used, reused, adapted, and shared.
As a network for teaching and learning materials, the web site offers engagement with resources in the form of social bookmarking, tagging, rating, and reviewing. OER Commons has forged alliances with over 120 major content partners to provide a single point of access through which educators and learners can search across collections to access over 24,000 items, find and provide descriptive information about each resource, and retrieve the ones they need. By being "open," these resources are publicly available for all to use, and principally through Creative Commons licensing, many thousands are legally available for repurposing, modifying and improving.
