An Open Access repository is a database or a virtual archive established to collect, disseminate and preserve scientific output like scientific articles and datasets and make them freely available. The action of depositing material in a repository is (self)archiving. Depending on personal preferences or publisher's policies, the author can make his work available in Open Access or (temporarily) restrict the access to it.
Repositories can be either linked to an institution or department or linked to a research field or subject, i.e. Institutional or Subject Repositories.
When using the OpenAIRE deposit service you will be guided through the steps of deposition and also if possible guided to a relevant repository (check out the list of compatible repositories). OpenAIRE uses data from the Directory of Open Access Repositories, OpenDOAR, and from the Registry of Research Data Repositories, Re3data.
- Subject based repositories are repositories oriented for research output from one or more well defined research domains. Classic examples are ArXiv and Europe PubMed Central. All researchers working in certain subject areas can make use of subject repositories – regardless of their affiliation or geographic location.
- Institutional Repositories are repositories that are maintained and curated by institutions - very often the library. Repositories collect, curate and make the research output of an institutions available on the Internet. As a rule, depositing is only possible for researchers affiliated with the institution.
- A data repository is a digital archive collecting and displaying datasets and their metadata. A lot of data repositories also accept publications, and allow linking these publications to the underlying data. Some examples are Zenodo, DRYAD, Figshare.
Please visit the OpenAIRE helpdesk if you are having trouble finding the best suited repository for you. If you do not have a repository to deposit your article in then you can use the Zenodo repository, hosted by CERN.
