In the "golden road" scientific work is directly published in an open-access journal or by an open-access publisher.
The costs which occur by publishing open access journals are covered via different models.
In the author-financed model the author pays the publication fees or article-processing charges directly.
Another possibility is financing the fees via institutional memberships in some publication plattforms (such as BioMedCentral).
Some journals do not require any fee. The Journal for Music and Performance (Act - Zeitschrift für Musik und Performance
) for example is published at the University of Bayreuth. Funding from the DFG could successfully be raised for this journal.
In the "green road" scientific work is published via a document server or an institutional repository. In case the work has already been published it is a so called parallel publication. Specific scientific document servers exist for certain scientific disciplines (such as arXiv, SSOAR, etc.). The University of Bayreuth provides a publication and document server called EPub Bayreuth
where members of the University of Bayreuth can publish their work.
