The term ‘open access’ has been around for decades… you may have also heard of open science, open research, or open scholarship. What do they all mean, and how are they relevant to your research practices? This talk will be theoretical: we’ll go through the different types of scholarly publishing models and their history, as well as the role preprints play in all of this – and how Francis Crick nearly disrupted an early open peer review experiment. It will also be practical: we’ll discuss how and why to make your research outputs open, as well as the specialist support that the Bodleian Libraries can provide.
