Front matter and back matter refer to information that appears at the beginning and end of a book, respectively. The exact terms and content of front matter and back matter typically vary depending on the type of book.
Front matter usually includes the title page, copyright page, dedication page, table of contents, and a list of illustrations, if applicable. It serves as an introduction to the book, providing context and additional information the reader needs before diving into the material.
Back matter often includes the glossary, appendices, index, and bibliography. It is additional material that supplements the main text but doesn't necessarily provide essential information. For example, if a book contains difficult terminology, the back matter could include glossary with definitions to help the reader makes sense of the terms.
