The section that gives a brief outline in book is called?

The section that gives a brief outline in a book is typically called a Table of Contents.

Here's why:

* Outline: The Table of Contents provides a structured overview of the book's contents, outlining the chapters, sections, and sub-sections.

* Brief: It offers a concise summary, listing titles and page numbers, but not detailed explanations of each section's content.

While some books might have other sections that provide outlines, the Table of Contents is the most common and widely recognized.
