Is there a certain way I have to cite a copyright protected work that I reproduce in an assignment or thesis?

Not usually. Generally, you should follow the style guide recommended by your instructor or used in your discipline to identify all material you did not create, in any medium. Your readers will assume that you have adhered to any applicable copyright laws and policies.

However, there are circumstances in which you may be requested or required to include certain information in a citation. Creative Commons licenses require that you indicate which license applies, and link to the license details if possible. An individual license or permission from a creator or publisher may also require that you include certain information. In these cases you should fit this information into your discipline's style guide if possible. You can ask a librarian for assistance with citations.
