The theme for this year’s 9th International Open Access Week, to be held October 24-30, is “Open in Action.” International Open Access Week has always been about action, and this year’s theme encourages all stakeholders to take concrete steps to make their own work more openly available and encourage others to do the same. From posting pre-prints in a repository to supporting colleagues in making their work more accessible, this year’s Open Access Week will focus on moving from discussion to action in opening up our system for communicating research. Established by SPARC and partners in the student community in 2008, International Open Access Week is an opportunity to take action in making openness the default for research—to raise the visibility of scholarship, accelerate research, and turn breakthroughs into better lives. This year’s Open Access Week will be held from October 24th through the 30th. The “Open in Action” theme will also highlight the researchers, librarians, students, and others who have made a commitment to working in the open and how that decision has benefited them—from researchers just starting their careers to those at the top of their field. International Open Access Week is a global, community-driven week of action to open up access to research. The event is celebrated by individuals, institutions and organizations across the world.
