Digital Commons Network"The Digital Commons Network brings together free, full-text scholarly articles from hundreds of universities and colleges worldwide. The Network includes a growing collection of peer-reviewed journal articles, book chapters, dissertations, working papers, conference proceedings, and other original scholarly work."
Essentially, this searches university repositories of work done by their students and faculty that use the Digital Commons platform (a large part of the market). Hamline has implemented our own Digital Commons, so we are a part of this Network.
