Google ScholarMany universities now make dissertations freely available on the web. Use Google Scholar to either find citations or see if those citations located in Dissertations and Theses or PsycInfo are available freely on the web.
Alternatively, you can do a Google or Google Scholar search, but here's a tip:
search words site:.edu
How does this work? Your result set should only have sites with your search words from websites ending with .edu (educational websites).
