The best way to locate articles is through the library databases. Go to Databases by Subject and look under the category Current Events & Controversial Issues to find a list of relevant databases. You can also perform a search in the databases below.
Remember not to write sentences in the search box. Search by topic or keyword.
Look for additional keywords or subjects offered. Think about synonyms for the phrase "American Dream." You may find them in an encyclopedia entry. Why not search for "American Dream" in the Encyclopedia Britannica and see whether there are other phrases you can use in your research.
Also make sure you look for toolbars that provide print, email, and citation options.
