Library search engines (databases) are a great place to find scholarly journal articles or other sources for your paper. Each search engine has a different flavor/subject area it covers. If the full text isn’t right there, click the Find It button. If we don’t have the article, you can request it from another library by clicking the “get this article or book chapter” link. (The turnaround time on this is usually about 2 days.)
