"The internet lets us share perfect copies of our work with a worldwide audience at virtually no cost. We take advantage of this revolutionary opportunity when we make our work "open access": digital, online, free of charge, and free of most copyright and licensing restrictions. In this talk, Peter Suber - Director of the Harvard Open Access Project - shares insights from his new concise introduction to open access - what open access is and isn't, how it benefits authors and readers of research, how we pay for it, how it avoids copyright problems, how it has moved from the periphery to the mainstream, and what its future may hold. This event includes questions and responses from Stuart Shieber (School of Engineering and Applied Sciences), Robert Darnton (Harvard University Library), June Casey (Harvard Law School Library), David Weinberger (Berkman Center / Harvard Library Innovation Lab) and more."
