Google Scholar is the most comprehensive database of research literature, but it does not have an editorial assessment of the quality of the sources. Therefore, the database includes different types of «green» OA material (preprint, postprint and published versions) and «gray literature», ie research literature that is not peer-reviewed, such as conference papers or research reports.
OpenDOAR. International database of open archives and their sharing policy.
OSF Preprints. Open platform that collects preprint versions and openly distributed manuscripts of scientific articles in everything from economics, architecture, social sciences and medicine.

Open subject-specific archives - for example:
bioRxiv. Open archive of preprint versions of articles from medical research.
PubMed Central (PMC). Archive with open articles in disciplines such as medicine and biology.
Physics, mathematics, computer science

Norwegian open journals in the humanities and social sciences (Norwegian text). From 2017, a selection of central Norwegian journals in the humanities and social sciences are openly available. It is extended with 28 open journals from 2021. There is no central database for these journals, so one must look them up invividually.
Researchers associated with a Norwegian research institution often have access to so-called reference databases, where one can do advanced searches for relevant research literature. The commercial bases Web of Science from Clarivate Analytics and Scopus from Elsevier are the most used. These databases provide the opportunity to filter on open access, so that it will then be possible to get an overview of relevant open literature. Contact the library at your institution if you are unsure whether you have access or if you need guidance in using the tool.
There are several browser add-ons that can simplify the process of finding legally open versions of research literature that lie behind the payment wall at the publisher. The tool is downloaded and installed in your browser. Search as you are used to and use a plug-in that shows you where you can find open versions of an article.
Contact an article author or another researcher.
There are several social media outlets where researchers can both build networks and exchange information. For example, ResearchGate and Academia are popular services. Be aware, however, that many researchers share more than they are strictly allowed to share with respect to copyright. Check the publisher / magazine's policy in the Sherpa / Romeo database, or on their website.

Articles that are not freely available and that your library does not have in its collections can be obtained from other libraries. Search for and order the article in Oria, and the library will try to get it for you.
