This module is part of the RDF - Researcher Development Framework series of modules and workshops. It has been designed to give postgraduate and early career researchers a practical overview of the principles of Open Access and Open Access publishing of research output. The aim is to encourage researchers to embed best practice within their work from the earliest opportunity. Topics covered include: the history and principles of Open Access and debates surrounding it, funder mandates on Open Access and tools to support researchers with compliance, copyright and licences in relation to author rights and user permissions, guidance on publishing a paper in Open Access publications, and institutional tools that support researchers in making their research output Open Access.
