Open Access in Astronomy: How did it happen, what is the status, and where are we going?
Astronomy has traditionally been an open science with a wide-spread attitude of sharing and exchange of best practices. Outside of astronomy, a strong movement towards Open Access Publishing has taken place during recent years, which is now affecting all scientific subject areas.
In this presentation, we will give a quick overview of what Open Access is and what it means for astronomy, and will review the current publishing models of core astronomy journals. A special focus will be the support libraries provide to scientists to make the best use of the Open Access options available to them, as well as the ways in which librarians help to shape movements in scholarly communication in order to establish a more collaborative, transparent publishing landscape.
