Usually, you can publish the preprint of an article before acceptance in generic repositories like Arxiv and in the institutional repository Minerva. This depends on the publisher and is not always possible. If you have doubts, consult the Knowledge and Transfer Management Unit.
Once a publication is accepted, it must be uploaded to XiCi for publication on the CiTIUS website: Add publication. In the case that you have preprints, you may need to update them with the DOI and journal information. For example, Arxiv allows you to update the DOI and journal reference from the author's account in the list of published papers.
The institutional repository Minerva allows the archiving of publications by indicating the embargo period of the journal. Thus, articles are made public automatically once the embargo periods are fulfilled.
You can check the self-archiving conditions of journals on the following portal Sherpa Romeo, a search engine and repository of this type of information.
Funding institutions may have requirements for the dissemination of articles (e.g. immediately for Horizon Europe projects and 1 year for national projects). Some publishers allow self-archiving of publications when their policies conflict with the policies of funding agencies, which can be utilized to publish articles via “green route” before the embargo periods are fulfilled.
Profiles on Google Scholar also allow the archiving of pdf documents associated with publications. It is advisable to check that the policies of the different publishers are met before uploading the pdf of a publication to Google Scholar.
