Essentially, there are two different approaches to Open Access. The so-called golden way is defined as measures that focus on Open Access primary publications, currently mainly Open Access journals. The so-called green way, on the other hand, means the additional provision of publications that have appeared in (closed-access) journals.
In addition, there is a greater grey area and diversity, which do not always make the interpretation of Open Access very easy.
As part of the exercise, you will search for open journals as well as open research data repositories and will deal more intensively with the basic ideas behind Open Access.
