Using copyrighted material

Own previously published work
Copyright exists to protect work from being copied, or changed, or quoted out of context by others without permission of the copyright owner.  This is normally you, the author unless ownership in the copyright has been transferred (for example, to a publisher). In some cases copyright belongs to the university or an organization that commissioned or sponsored your work. It is therefore possible that permission is required before authors may publish sections of their own academic work that has been published previously.
Despite owning the copyright, some publishers permit authors to make own publications available on their personal web pages. Always read your copyright transfer agreement with the publisher carefully to make certain which restrictions apply.

Third party copyright material
Material freely available on the web may be protected under copyright law. Unless specifically stated otherwise, you may need permission from the copyright holder to include such material in a publication, to make third party material available on your website, or to distribute multiple copies for teaching purposes (other than a “limited amount”: see below.) This applies equally to material only available via a restricted network such as intranet and Studyweb.

Linking to another web page
Linking to a homepage where the hyperlink to the material itself is to be found is unlikely to violate copyright law. This is a grey area of copyright law because hyperlinking, although not actually copying the material itself, could be seen to be authorizing others to make a copy of the material by means of the link provided. Although a hyperlink to someone else’s material is not illegal, storing a digital version of the material itself on a network computer is a form of publication for which permission by the copyright holder is required.

Copying for educational purposes
Copyright law permits (digital) copying of a limited amount of a publication without permission for purposes of non-commercial research, instruction, or private study. Acknowledgement of the source is required and must appear on each copy distributed and reader royalties must be paid. On intranetpages Information Expertise Center Tu/e staff will find  Agreement on Reader Rights with PRO.

It is not only a matter of professional integrity, but also a matter of copyright law that a writer should not quote the ideas or the work of others without proper acknowledgement: Acknowledge all sources that you have used and do not forget to acknowledge the source of illustrations, tables, and graphics.
