In this episode of the Times Higher Education podcast, we talk to two experts – one in the US and one in the UK – about open access, the global movement that aims to make research outputs available online immediately and without charge or restrictions. Heather Joseph has been an advocate for knowledge sharing and the open access movement since its earliest days. Based in Washington DC, she has been executive director of the Scholarly Publishing and Academic Resources Coalition (SPARC) since 2005, and is known for her policy work, leadership and international consultancy for organisations such as Unesco, the World Health Organisation and the World Bank. In 2021, she won the Miles Conrad Award, the National Information Standards Organization’s recognition of lifetime achievement in the information community, and her lecture as the recipient is a detailed history of the movement, its goals and strategies. Steven Vidovic is the head of open research and publication practice at the University of Southampton in the UK. A palaeontologist with a passion for scholarly communication and knowledge exchange for public benefit, he is also chair of the Directory of Open Access Journals advisory board and Southampton’s institutional lead for the UK Reproducibility Network, and he is a member of Jisc’s transitional agreement oversight group.
