Information about copyright

Creative Commons

What is Creative Common and why is it relevant?

Creative Commons Licenses are a type of open licenses that you can apply to your work to indicate you are happy to share the work under certain conditions.

They are sometimes described as an alternative to copyright, however Creative Commons does not mean you give up the copyright in your work, or your right to be acknowledged as the creator of a work.

Typically Creative Commons licenses are added to online content, and search engines are increasingly able to identify content that has been shared under these licenses because in addition to the legal document, there is a machine readable license.

There are six different license types, with the most permissive being the CC-BY (Creative Commons Attribution) License and most restrictive being the CC-BY-NC-ND (Creative Commons Attribution Non-commercial No Derivatives) license. The licenses allow you to specify if you wish your work to be used for commercial purposes and if you require the person re-using your work to share it under the same license, or if you are happy with derivative works being created from your work. 

Adding a Creative Commons License

It is relatively simple to add a Creative Commons License to your work. The first step is to visit the Creative Commons website and choose the license that best suits your needs. The instructions on screen make this relatively straightforward to choose between the six licenses types. If the work is a web page then you can copy a piece of HTML code to embed in your page, to add the license. Otherwise, you can include details of the license using the logos in the table  and the abbreviations, with a link to the license online.

One thing to note about adding a Creative Commons license to your work is that they are irrevocable, so once added to your work you cannot remove the license as people may have started using it.  

Creative Commons Licenses

License Type Abbreviation Description



CC-BY This license lets others distribute, remix, tweak, and build upon your work, even commercially, as long as they credit you for the original creation. This is the most accommodating of licenses offered. Recommended for maximum dissemination and use of licensed materials.

Attribution ShareAlike 

CC-BY-SA This license lets others remix, tweak, and build upon your work even for commercial purposes, as long as they credit you and license their new creations under the identical terms. This license is aligned with the “copyleft” free and open source software licenses which ensure that derivative works can never be put under more restrictive licensing terms than the original. All new works based on yours will carry the same license, so any derivatives will also allow commercial use. This is the license used by Wikipedia, and is recommended for work that incorporates content from Wikipedia and similarly licensed projects.

Attribution NonCommerical

CC-BY-NC This license lets others remix, tweak, and build upon your work for non-commercial purposes, and although their new works must also acknowledge you and be non-commercial, they don’t have to license their derivative works on the same terms.

Attribution NoDerivatives

CC-BY-ND This license allows for redistribution, commercial and non-commercial, as long as it is passed along unchanged and in whole, with credit to you. 

Attribution NonCommercial ShareAlike

CC-BY-NC-SA This license lets others remix, tweak, and build upon your work for non-commercial purposes, as long as they credit you and license their new creations under the identical terms.

Attribution NonCommercialNoDerivs

CC-BY-NC-ND This license is the most restrictive of the six licenses,only allowing others to download your works and share them with others as long as they credit you, but they can’t change them in any way or use them commercially.
