Articles tend to have a narrower, more specific focus, are relatively short, and can be more current than books. If you need to find information on a very specific topic or a very current one, it may help to search an article database.
Some article databases provide full text while most only provide references to articles.
Look out for the purple "Find it @ NU" button among your database search results.
