Disseminating knowledge was once a costly undertaking. The expenses of printing, distributing, and housing the work of researchers and scholars left most research in the hands of publishers, journals, and institutions in a system that has evolved over centuries. And the licensing model that has arisen with that system butts heads with the quick, simple, and virtually free distribution system of the net. The key to breaking free of the traditional licensing model locking up research is the promise of the “Open Access” movement. And the movement has already made significant strides. Over the summer the United Kingdom was enticed enough by the potential for greater innovation and growth of knowledge to propose Open Access for any research supported by government funds. But Open Access still remains a wonky, hard to understand subject. Today, Peter Suber — Director of the Harvard Open Access Project — shares insights with David Weinberger from his new guide to distilling Open Access, called simply Open Access.
