How is Google Scholar different from Open Access or free institutional access?
 
Our efforts through Google/Google Scholar are about expanding the availability of dissertations and theses beyond the scholarly community.  Obviously, this is not intended to substitute for the kinds of liberal and/or free access that researchers normally have to dissertations and theses through institutional subscriptions to the ProQuest Dissertations & Theses (PQDT) database. And of course, dissertations and theses published under our new Open Access Publishing option will be available for immediate, full-text download from ProQuest’s PQDT Open web site, and the bibliographic data will also be searchable via Google/Google Scholar.
