Grey Literature Archiving Pattern in BRICS Open Access Repositories

The data for this study was retrieved from the Bielefeld Academic Search Engine (BASE) by conducting an advanced search on different document types archived by OA repositories of the world and BRICS. Findings of the study indicated that reviewed literature is the major document type archived in open-access repositories around the world.

European and Asian repositories archived the highest number of grey literature document types. Among BRICS, Brazil has dominated over the other four nations by contributing the majority of grey content, reviewed literature, and non-textual documents.
