How to find openly accessible literature?

Many articles both in open and subscription-based journals are legally and freely accessible. There are many different ways you can get access to these.

​​​​​Open Access entails free, digital access to research results.

The University Library subscribes to many databases and e-journals. This gives you free access to a lot of research, both that which is openly accessible and that which is not. Nevertheless, you might need to search for openly accessible material other than this, and this page gives an overview over different ways of gaining access.​

Scholarly sharing/con​​tact the author

Usually, authors are allowed to share articles even though they are not openly accessible. This is called ‘scholarly sharing’. You can e-mail the author directly and ask for a copy; most authors are happy to share their articles with others, depending on the agreement they have with their publisher. You can also easily request access through the social research networks ResearchGate.net and Academia.edu.
