Copyright must be taken into consideration
The author has the right to determine the use of their work. You can analyze copyrighted material in your research and describe it in your own words, but you cannot, for example, attach it as such to a thesis.
You can attach citations from public works made by others to your thesis, if there is a justified scientific reason for doing so. The right to quote does not imply the right to copy. For example, if you do interviews, you should ask for permission to use quotes.
Please note that everything posted online cannot be freely used.
Licenses define the terms of use and sharing for different kinds of materials. A licence can be given e.g. to publications, educational recourse, research data, photographs and metadata. Creative Commons license system (CC licences) is the most commonly used system in the scientific world.
The license does not remove your copyright. The established practices of references and citations must be followed also when using licenses. You must always offer the information about the chosen license and a link to the license description. Possible modifications must be mentioned.
You can find more information about copyright licenses in the Library's Open Science Guide.
