The Times Index is also useful in locating material in other newspapers because it gives a clue to the date of an event. Brief synopses of articles answer some questions without having to go to the paper itself. Citations include date, page, and column number. Its arrangement and subject headings are unique, and frequently difficult to use. You can use this index to follow the course of particular events through its pages.
Narrow topics are often cross-referenced to an article under a broader topic.
