LiU E-Press is an Open Access publisher, indicating that all of the publications found at LiU E-Press are freely available to anyone with an internet connection. Open Access means that a reader can download a document, but further ditribution and use of the work must be clarified. What is not clear from the label Open Access is what a reader can do with a document that they find here. The copyright is held by the author(s) and as such there is an ambiguity. To avoid this problem, Creative Commons licencing is often used. Creative Commons licences are used very widely (e.g. for music, video and documents) to specify what a user (usually a reader, in the academic community) can do with a document.
There are a number of different Creative Commons licences, each allowing a user to do different things with a piece of work. The most flexible licence is what is referred to as an “attribution” licence. Under this type of licencing a user can read, distribute, re-work and even sell a work (or parts of it) so long as credit is given to the original author. At E-Press, we have decided to recommend that authors use the “Attribution Non-commercial” licence which allows users to distribute the work and to re-work it but not for any commercial purposes, without the author's permission.
A various number of journals uses the Creative Commons to clearly clarify what is allowed and not allowed with the publication:
