What is a database?
A library database is a collection of citations, and sometimes full-text, of articles, reports, and other types of academic sources that are available in libraries. Most of the citations in database come from scholarly journals, although some also include popular (non-scholarly) magazines and newspapers.
Some databases are general (like Academic Search Complete) and some are specific to disciplines and subjects. Finding the right database to search in a good first step in your research process.
When you're trying to come up with search terms, there are a few things you want to keep in mind.
