Copyright

If you write a doctoral dissertation, please inform yourself about copyright. Copyright protects you as an author. Publishers may ask you to transfer the copyright to them, but you are not obliged to do so.

The University is entitled to retain a copy of your dissertation at the University Library and to use it for its academic teaching and research. However, you possess the copyright to your own work, unless you have explicitly transferred it to someone else. Is your doctoral dissertation being published? Pay close attention to any transfer of copyright statements in the contract with your publisher. This also applies if you want to publish articles or chapters from your dissertation in other media.

Retaining copyright

You are not obliged to transfer the copyright to a publisher. SURF has produced a short film explaining how and why you can choose to retain copyright.

Previously published articles

If you include previously published articles in your doctoral dissertation, for instance articles that have been published in an academic journal, always check whether the publisher possesses the copyright. You may need official permission from the publisher to publish the article in your dissertation. It's your own responsibility to make sure you have permission. You can use this standard letter for publishers if the publisher possesses the copyright.
