Licensing your copyright
As a copyright owner, it is for you to decide whether and how to license use of your work.
An exclusive licence could be granted, but remember that this enables the licensee to use the copyright work to the exclusion of all others, including the copyright owner. Any licence agreed can relate to one or more of the economic rights and can also be limited in time or any other way. It is a contractual agreement between the copyright owner and user. Sometimes people may be able to argue that a copyright work is subject to an implied licence even when there has been no agreement about a licence.
Some people prefer to allow limited access to their work without charge.
One way to do this is by using a
Creative Commons licence 
.
