Many article databases now offer a personal (free) storage feature that lets you save the results of your article searches. You can also use this feature to set up a journal or search alert to notify you when an article of interest is added to the database.
It will even create a properly formatted citation, in the style of your choice. Click on the title of your article and look for the yellow "cite" icon on the right.
Use the Reference feature in MS Word 2007 to add citations in your text while writing. At the same time, Word will build a reference list for you with the sources you add. For a complete tutorial, visit the Create a bibliography help pages at Microsoft Office.
