Most periodical indexes organize their records using a list of approved subject headings. This allows you to find all the articles about your topic under one term.
How do you find the approved subject headings? Some indexes provide a list of subject headings. If you search for a word that is not in the index, it may suggest an approved subject heading you could use.
In this example, there are 1,712 articles about the Internet in this database. If you looked for articles using the words Information Superhighway, this database would direct you to use the subject heading Internet.
