There are no good Open Access journals in my domain. How could I possibly comply with Open Access mandates?

If you have checked the Directory of Open Access Journals, DOAJ and haven't found any relevant journal for the results you would like to publish, you can follow the Green Road to OA.

The Green Road refers to the parallel publication of a version of the manuscript in an open repository, or self-archiving. Open repositories can be institutional, as our own SERVAL, or disciplinary. The publication is often delayed (embargo period) and allowed only for the author accepted manuscript (AAM), also known as postprint. This is the manuscript accepted for publication (post peer-reviewed), but before all copyediting by the editor. There are no costs for researchers to follow this road.

Below you can find a scheme that shows the available roads to Open Access.
