Creative Commons provides licenses and tools which allow anyone to grant  copyright permission for their creative and academic works and enable others to copy, distribute and make use of those works. This means that you can use most Creative Commons licenced works in your short course teaching outputs without having to pay or ask for permission.

When using this material you should check any restrictions the copyright owner has applied as there are several different CC licences available.

• We consider online short courses to be non-commercial, so you can use content with an ‘NC’ or ‘non-commercial’ licence clause. 

• You can use materials with an ‘SA’ or ‘ShareAlike’ clause if you are quoting or using the content ‘as is’. You should not remix, transform or build up on ‘SA’ licenced material as you will not be sharing it under the same licence as the original. 

• You can use materials with an ‘ND’ or ‘NoDerivatives’ clause if you are quoting or using the content ‘as is’. You should not remix, transform or build up on ‘ND’ licenced material as derivatives and adaptations are not permitted.
