Below are some websites you may find useful when tracking down background research on your chosen topic. Be aware, this is by no means an exhaustive list; use the sites here as a starting point.
Most literature indexes do not have the actual journal articles included within them. Instead, these indexes just contain information about the article, e.g. titles, authors, abstract.
When you find an article of interest in an index, click the "Find It" button by that entry to get to the full text. If we have a subscription, "Find It" will provide a link to the journal article. (Or if we have the print, it will provide a link to the catalog with the location and call number.)
(A few databases, like Academic Search Complete, include full text for some articles. These databases may allow you to search only for articles available in full text, but be aware that you are only searching a small portion of the articles we actually subscribe to.)
