The benefits of open access are familiar to many librarians. Making publicly funded research openly accessible serves a common good by advancing discovery and innovation, enhancing public welfare, providing an evidence base for sound policy, as well as many other societal benefits (Canadian Association of Research Libraries, 2013).   We have a short list of summaries this issue. The first article summarized investigates librarians’ perspectives on their role in promoting open access and the barriers and requirements for successful promotion. Next is a summary of an article that explores faculty perspectives on and experiences with open access and sharing of unpublished open content. The final evidence summary looks at an article that showcases techniques for archiving open access articles in an institutional repository. We hope these summaries provide useful to librarians involved in, or simply interested in, open access endeavors.   References   Canadian Association of Research Libraries. (2013).
