Creative Commons explained

Creative Commons and how it helps us share digital content (YouTube, 5m30s) explains how to share downloaded digital content legally using Creative Commons licences.

What is Creative Commons?

Creative Commons provides free copyright licences to offer a simple and standardised way to give permission to share and use creative works.

Creative Commons licenses - Most open to least open - CC0, BY, BY SA, BY ND, BY NC, BY NC SA, BY NC ND

The four different licence elements are:

 Attribution: You must always provide credit to the original author - BY

 Share-Alike: If you remix, transform, or build upon the material, you must distribute your contributions under the same licence as the original - SA

 Non-Commercial: You may not use the material for commercial purposes - NC

No-Derivatives: You may not distribute modified versions of the work - ND


For Open Educational Resources (OERs), try to use Creative Commons material with:

  • BY - This licence lets others distribute, remix, tweak, and build upon a work, even commercially, as long as they credit the creator of the original.
  • BY-SA  - This licence lets others remix, tweak, and build upon a work even for commercial purposes, as long as they credit the original creator and license their new creations under the identical terms.

Both these licences permit commercial use. If you are creating an open course or MOOC, that later is commercialised,  you can still use the resources if they have a BY or BY SA licence.

Attributing resources

You must acknowledge the creator and include any copyright information when you use a resource.

The basic requirements are:

  • Name of the creator
  • Title of the work
  • The URL of the work
  • Type of licence it is available under and a link to the licence
  • If it has been modified.

Note: We don't recommend using any materials licensed CC BY 2.0 as it has been superseded and has strict attribution requirements that can make it easy to make a mistake. Materials licensed CC BY 4.0 are preferred.
