Database: an organized collection of information, usually pertaining to a particular subject

A database is a great tool to help you locate quality information. Think of databases as huge electronic filing systems. They must be highly organized for people to easily find the information they need.

The most common types of databases you will encounter in the library are the online catalog and online periodical indexes. These indexes point you to articles relevant to your topic which are published in journals, magazines, newspapers and other sources.
