Many of the teaching, learning, and resource materials on OER Commons reside in the public domain or have been released under an open license that permits no-cost access, use, and redistribution by others with no or limited restrictions. These privileges cannot be revoked as long as you follow the license terms.
Each resource has one condition of use/copyright label. These labels help you quickly distinguish whether a resource can be changed or shared without further permission required. In addition, you can find the specific license or terms of permitted use for each resource.
Watch for the license symbols listed below.
