This document summarizes the history of open access advocacy at the University of Nottingham. It discusses how the university established its first institutional repository in 2006 and began a central open access fund. It then outlines the advocacy efforts over time, including meetings with faculty research committees from 2010-2014, which led to new open access policies. Currently, open access support is provided by the library and research services. Challenges remain in fully understanding open access across faculties and upskilling the support team. Next steps include launching a new communications plan and website, and increasing direct outreach to academics.
