TOC in epub

The Table of Contents (TOC) in an EPUB file serves as a navigational tool that outlines the structure of the document, allowing readers to easily access different sections or chapters. Typically, it is generated from the document's metadata and can be represented in both a linear format and as a hierarchical list. The TOC is crucial for enhancing user experience, especially on e-readers, by providing quick links to various parts of the text. Properly formatted TOCs are essential for accessibility and usability in digital publishing.
