The best way to locate articles - from magazines, newspapers, scholarly journals, and law reviews -- is through library databases. Here are a few databases that you may find particularly helpful:
LexisNexis has law reviews, in addition to cases and regulations. Law reviews are journal articles with analysis.
For law reviews, select "Search By Content Type," then "Law Reviews."
Select the most important 2-4 words related to your topic. Put the word AND between each new word or idea; this tells the database to look for resources with ALL your terms.
patriot act AND terrorism
Use quotation marks ( " " ) around phrases (two or more words); this tells the database to look for the words in a specific way.
"patriot act" AND terrorism
Most databases use the asterisk (*) to truncate a word; this tells the database to look for all words that have the same base. In the example below, search results would include "terror," "terrorist," "terrorists," and "terrorism." Note that in LexisNexis an asterisk only replaces one letter; in LexisNexis use the exclamation point (!) at the end of the word to find words with multiple endings.
