It’s best to insert the Index as the last section in the book, after the Bibliography or the References sections. If the book has no Bibliography or References, then you can put it after the Glossary section. If the book also has no Glossary, then you can put it after the Notes section.
- The Chicago Manual of Style book: This book has the Bibliography section with its contents, then comes the Index after it.
- The Children and Drug Safety book: This book has the “Acknowledgments” section, then the “Notes” section, then comes the “Index” section after the “Notes” section. Because this book has no Bibliography, or References, or even a Glossary section, it has been put after the “Notes” section, and this is a right behavior.
- Finally, i have checked the Guide To Practical Health Promotion book. This book is divided into 2 parts, followed by an “Appendix” section, so the “Index” comes after this “Appendix”, because this book has none of the other sections that we have mentioned in the other books.
