Faculty members at the Massachusetts Institute of Technology have voted to make all of their scholarly articles available to the public, free and online. MIT and faculty members will let others use the articles in any way except to make a profit. Individual authors may opt out on an article-by-article basis. "The vote is a signal to the world that we speak in a unified voice; that what we value is the free flow of ideas," said Bish Sinyal, chair of the MIT Faculty and the Ford International Professor of Urban Development and Planning.
