Chapter A chapter is a section of a book, usually organized around a topic or issue. Each chapter is organized with an introduction, body and summary, much as a book is. Footnote A note at the bottom of the page with information about the source of a reference or a comment about the content. The sources of data or information used in writing the document are the references. This refers the reader to the citation in the footnotes, endnotes or to the bibliography at the end of the chapter or near the end of the book.
References are one of the most valuable parts of a book.
Further Reading The author may provide a list of related readings not necessarily referred to in the text. The lists of citations provided are valuable in finding further information. Explore the textbook beyond the text in the body of the book. Appendix Sometimes important supplementary, statistical or explanatory information is found in the appendices at the end of the chapter or near the end of the book. These are usually too lengthy to fit in the body of the chapter.
