The Copyright Information Office of the University library has a website with main rules for just use of publications in teaching:
- You can always link (not to illegal content); if necessary make an SFX-link.
- Using Open Access content, such as available in the Leids Repository, is always allowed and recommended.
- Using magazine content with which the university has a license agreement with the publishers, is allowed; look at the Term of use licensed digital resources. The list of publishers licensed do not pertain to book articles.
- Short copies are allowed (if bought through foundation PRO), if you comply with citation. The readerregeling(?) defines what a short copy is based on the amount of copied words; images, graphs, tables, overviews, photos, illustration etc. all count towards the maximum (of 200 words). Have a look at the main rules.
- For longer copies you need to apply for permission and payment. You can do this through the Foundation PRO portal; have a look at how long copies without license and links are to be signed up.
- Hoe to digitally publish education materials, has been summarized by the Copyright Information Office.
