In this webinar we will talk about what pre-prints are, where you can find them, and what value they can bring. Are pre-print servers used more widely in certain subjects, and why? And what impact does posting pre-prints have on an article's later publication, if any? And do we know if articles are more or less likely to be published open access if a pre-print was posted? Join us for an hour of short presentations and a lively discussion with panelists from across the research eco-system.
