Google Scholar enables you to find more articles for your research outside the library. It also has a Cited By feature to help you track the number of times an article has been cited and where the article has been cited. Any articles you can't find in the library can be requested through ILL.
You can utilize Google's Advanced Search to help narrow your results from the start:
Use Google's search box structure on the advanced page to enter the related terms in your search (i.e. girls/women/female) and create a Boolean search string (see box to the left)
Use the "Search within a site or domain" box to screen out .com sites
The domain name of a site can give you a good idea of what content you might find there:
.com - "Commercial" A for-profit site selling something (sometimes information).
.net - "Network" Usually similar to .com
.org - "Organization" A non-profit, but likely has an agenda/opinion.
.edu - "Education" An educational institution, college, or university.
.gov - "Government" Sponsored by the US government.
