Creative Commons Licences
Creative Commons licences enable authors to assert copyright in their work while at the same time encouraging others to reuse their content, subject to certain conditions. You can choose from a range of of CC licences, depending on the types of reuse which you are happy to license. The copyright owner can choose, for example a licence which either allows or rules out commercial reuse of their work.
The Creative Commons Licences are very suitable for material posted on the internet, where the copyright owner has no commercial reasons to protect their content from being reused by others or wishes to encourage reuse.
The licence accompanying the material (usually represented by a simple logo that links to more in-depth information) will clearly define what types of reuse are permitted by the creator.
