The Index, which is usually located in the back of the
book, is an alphabetical list of the specific subjects in the book,
along with the corresponding page numbers. Indexes may provide names,
dates, events, geographic locations, and other detailed terms related to
the contents of the book. Browsing an index is an excellent way to
identify exactly where in the book relevant information may be located.
An index can also provide subject terms and keywords that might be
useful for further research on a topic.
