Epub (Electronic Publication) is an open file format that is widely used for distributing digital publications such as e-books, magazines, and academic journals. It offers several advantages over traditional PDF formats, including enhanced accessibility, interactive features, and device compatibility. Understanding the fundamentals of EPUB can empower authors, publishers, and readers to optimize their digital reading experience.

The Anatomy of an EPUB File

• Sigil: A free and open-source EPUB editor
