Is publishing in a "pure" Open Access journal the only way to do Open Access?

NoNo..

Publishing in a (pay-to-publish or free-to-publish)Gold Open Access journal constitutes(pay-to-publish) is the Gold Roadroute towards Open Access.to Open Access works(Gold OA). Works published via the Gold Roadroute are immediately openly accessible and are usuallygenerally protected by an open licence,licence such as Creative Commons .

However, there isare another alternative wayways to publish in Openopen Access,access: namelythe Diamond route (Diamond OA), the Green Roadroute (Green OA), and the Hybrid route (Hybrid OA).

The Diamond route (Diamond OA) is a model in which neither readers nor authors pay fees. Publication costs are covered by institutions, universities, libraries, or public funding. This model aims to guarantee equitable open access, without financial barriers for researchers, while ensuring the immediate dissemination of publications.

The Green Roadroute refers to the parallel publication (or self-archiving) of a version of the manuscript in an openinstitutional repository, or self-archiving.repository. Open repositories canmay be institutional, such as our own SERVAL,SERVAL/IRIS, or disciplinary.discipline-based. The publicationPublication is often delayed (embargo period) and allowedis only permitted for the author accepted manuscript (AAM), also known as postprint.the post-print. This is the manuscript accepted for publication (postafter peer-reviewed),peer review) but before allany copyeditingtypesetting by the editor.publisher. There areis no costsadditional cost for researchers to followfollowing this road.route.

The Hybrid route (Hybrid OA) concerns subscription journals that offer the possibility of making certain articles open access upon payment of publication fees. In this model, a single journal may contain both restricted-access and open-access articles. Although this option allows immediate access to the relevant articles, it is criticised for the risk of "double-dipping."
