In this talk I'm trying to answer the following questions: Why publishing open access? What are the guidelines from our institutions? What are the different options out there? What are the advantages? The pitfalls?... I'm starting with quick definitions and a clear articulation of the problems we're facing regarding the open publication of our papers. Then I'm walking you through the different routes to open access (gold, green, hybrid, diamond), and finish with presenting emerging models that depart from the traditional publication system. I hope this will change how you approach your next submission!
