Indexes are the tools used to find articles in periodicals (journals, newspapers, magazines). An index will tell you which journals have published articles on your topic.
Indexes come in both print and electronic versions.
Electronic online indexes are called databases. Although these databases have a web-interface, they are NOT FREELY AVAILABLE ON THE INTERNET. They require a paid subscription. However, Woodruff Library subscribes to a great number of databases, so as an Emory student, you can freely access these databases.
The easiest way to select the best index/database is to use the Databases@Emory page. Choose your subject from the drop down box and click go, and you will get a list of databases that cover your subject. A short description of the database is included so that you can make sure it's going to meet your needs.
You can also refer to the Research Guides for lists of indexes/databases recommended by librarians.
