Open access publishing has been relatively slow to take hold in chemistry in comparison with other STEMM disciplines. Why is this? What are the benefits of open access publishing for chemists? What encourages them to publish as open access? What are the perceived barriers or disincentives to open access publishing? How has open access publishing affected the role of librarians in the way they support researchers, and how do they facilitate it at their institutions? How has the move towards doing open science influenced all of this? This presentation will explore, from an academic librarian's perspective, the impact that open access publishing has had on chemists and how this might change in the future.
