This database of scholarship is not comprehensive, but it can be very useful for recent dissertations and increasingly for open-access scholarly articles.

Google Scholar offers a "cited by" feature - it will display a list of documents which cited the document you originally retrieved. This can be useful in tracing important research forward in time or in determining how influential a source has been. The list of citing documents only includes those available in Google Scholar, though.
Look for the Find It @ Bowdoin College link to access available full-text articles. Or, go into the preferences of Google Scholar and select Bowdoin College from Library Links.
