The aim of the Open Access movement is that all published research should be freely available at no cost for the reader. Open Access is included in the Open Science umbrella concept, aiming at opening up several parts of the research process. Apart from Open Access, Open Science includes open learning resources, pre-registration of research plans, open-source codes, open peer-review and open data.
The main idea is that this helps increase the quality of research and ensures that research results will be universally available. The library can be supportive throughout the research and publication process. The availability helps articles that are published Open Access to be disseminated quickly and increase the number of citations. Authors retain copyright instead of signing it over to the publisher.
A common model of Open Access publishing is moving the cost from the reader to the author, where authors pay a publishing charge (APC - author/article processing charge). In many cases, the library can pay this charge.
