This presentation has been created for a course which covers the practical steps you need to take in order to ensure that work submitted for publication by University of Cambridge researchers is compliant for REF2021. It includes the principles of open access and open research, and guides the reader through the necessary steps to meet the open access requirements of REF2021. It highlights the key processes for uploading work to Symplectic, including choosing the right version of a work to upload (activity). It is of particular benefit to those who administer the uploading of research outputs to Symplectic Elements to make them open access.
