Open Access Roads
There are several ways to make a publication freely accessible, often illustrated as roads or paths.
The Gold Road consists of publishing the results of one's research in an Open Access journal or in an Open Access book. Access to the document is immediate and free for all on the publisher's website.
The author is sometimes charged publication fees (Article Processing charges or APC; Book processing charges or BPC), which can often be covered by the Swiss National Science Foundation (SNSF), or even by the UNIGE's publication fund under certain conditions.
100% Open Access journals are listed in the Directory of Open Access Journals (DOAJ), and books in the Directory of Open Access Books (DOAB).
By following the Green Road, authors publish in a journal (often available by subscription) and deposit a freely accessible copy of their article in an archive of their choice, e.g. the Archive ouverte UNIGE, and/or in a disciplinary archive (arXiv, PMC, etc.)
Sherpa Romeo can in most cases determine whether a publisher imposes an embargo and/or restrictions on the version of the article that can be disseminated.
The hybrid model consists of publishing one's article in a subscription journal and paying an additional fee to make the article available in Open Access.
The risk with this model is that the publisher of the journal receives a double remuneration (subscription + APC). For this reason in particular, neither the SNSF nor the publication fund will provide financial support for publication costs in such subscription-based journals.
However, in the framework of Read&Publish agreements negotiated with certain publishers, journal subscriptions taken out by the Library include quota of articles that the institution's authors can publish in Open Access at no extra cost with these publishers.
