Green Open Access

Open Access as a model for publishing research results has many variations. One of them is Green Open Access. But what exactly is Green OA? In a sentence, it is a way of self-archiving. The researcher decides to submit the results of his/her research in a selected repository that is open, which means, that anyone has access to it and that the materials are free. So if you are considering self-archiving, but you are not sure what Green OA is all about, here is a list of useful links that should help you figure it out.
