What does a book index have?

A book index typically includes a list of terms or topics along with the page numbers where they can be found in the book. It helps readers quickly locate specific information within the book.

- Entries: These are the individual items listed in the index. They can be words, phrases, people, places, or things.
- Page numbers: These tell you where in the book the entry can be found.
- Subentries: These are additional entries that are related to the main entry. They are usually indented under the main entry.
- Cross-references: These are entries that refer you to other related entries in the index. They are usually indicated by the abbreviation "see" or "see also."
