In accordance with the Scientific Research and Innovation Activity Act and the Regulation on the Implementation of Scientific Research Work in Accordance with the Principles of Open Science, scientific research activity providers must ensure open access to all peer-reviewed scientific publications, research data and other research results within the framework of research co-financed by public sources at least 50%.
In case of publication of an article in a subscription journal (content accessible only to subscribers), the author ensures open accessibility by storing the corresponding version of the published work in the repository. As a rule, it is about saving AAM - Author Accepted Manuscript (postprint), i.e. the author's final, peer-reviewed manuscript accepted for publication.
At the same time, it is also necessary to take into account the publisher's (journal's) policies relating to storage or archiving of publications - it is mainly a version of publication, suitable for archiving and time availability of the saved document (immediate or with a delay - embargo).
The archiving conditions can be checked on the publishers' websites (under Article Sharing, Hosting Policy, Self-archiving Policy, Open access, etc.) or on the Open policy finder service.
As a rule, we store in the repository a PDF file of the author's final, peer-reviewed manuscript accepted for publication, which the author must obtain from the publisher during the processing of the publication.
