Before recommending, explore Ask these questions of the database:

What type of content is provided? How many publications are included? Years? How frequently is it updated? What navigational tools are provided? Are there tutorials? A help section? Search

tips? How are search results displayed? Can I save, email or print articles? RSS feeds? Which students would best be served by this?
