Green Open Access
With Green Open Access, the author makes a traditional publication, usually in a journal, and deposits either simultaneously or later a manuscript version of the article in Pure, or alternatively in another open repository (e.g., arXiv.org or PubMed Central). The deposited manuscript is typically the peer-reviewed postprint, but can also be the original submitted manuscript (preprint).
There is no cost connected to depositing Green Open Access, but postprints are generally subject to an embargo period of (typically) 6 to 24 months. Preprints have no embargo.
Gold Open Access
Gold Open Access is publishing in pure Open Access journals, where there is free and unrestricted access to all articles. Gold Open Access journals operate with a publication fee, known as an APC (Article Processing Charge), for publishing articles. The APC is usually covered by funding providers, the authors’ institutions, or by the authors themselves.
Hybrid Open Access
Hybrid Open Access is when individual articles are prepayed as Open Access-articles before they are published. Articles in hybrid Open Access journals will thus be a mix of Open Access articles and subscription-based articles.
As a RUC researcher, you have an option to publish without an APC in a number of hybrid Open Access journals. See the tab in this guide on Publisher Agreements.
Diamond Open Access
Diamond Open Access is publishing in Open Access journals that do not require payment of an APC. There is no cost to either publish or read articles in Diamond Open Access journals. Diamond Open Access journals and their platforms are typically funded or operated by research institutions, foundations, or university libraries.
In 2022, Science Europe, cOAlition S, OPERAS, and the French National Research Agency launched the "Action Plan for Diamond Open Access," which aims to develop and strengthen the opportunities for APC-free publishing.
In the DOAJ (Directory of Open Access Journals), you can search for discipline-specific Diamond Open Access journals.
Many researchers are unsure which manuscript version they are allowed to upload to Pure, including which embargo- and license rules apply. You are always welcome to simply submit your manuscript (pre- or postprint) to Roskilde University Library at rucforsk@kb.dk. We will ensure that the manuscript is correctly uploaded in Pure, and that any embargo periods as well as license and other requirements from the publishers are respected.
We recommend that you keep a copy of the Accepted Manuscript when/if you recieve it directly from the publisher.
If you are not the corresponding author on the article, you can ask them to send you the manuscript.
You can also, if it concerns large international publishers, take a look at the guide from Open Access Button as to how authors can get accepted manuscripts from the publisher's online manuscript systems.
