For the NCX and NAV, these are separate files that function like metadata, so placement isn’t a consideration. However, please be advised that placing the Table of Contents at the end may adversely affect the “last read” or “percent complete” feature that many eReading devices have. In that case, it is recommended to move the Table of Contents to the end of the eBook. Some authors find that the Table of Contents takes up too much space in the sample feature on Amazon. It is recommended to place the HTML Table of Contents after the dedication (or, if there isn’t one, after the copyright page) and before the acknowledgments, preface, introduction, epigraph, or first chapter-whichever comes first. The HTML Table of Contents is actually content within the eBook itself, while the NCX and NAV are embedded like metadata. While the way Tables of Contents are utilized varies from device to device, the essential purpose is the same: allowing the user to quickly access different parts of the eBook. For Adobe Digital Editions, the NCX is on the left pane. For iBooks, when you click on the Table of Contents icon, it pulls up a representation of the NCX (or NAV for EPUB3).
For Kindles you can click on the Table of Contents from the menu and this will transport you to the HTML Table of Contents.
The NCX on MOBI eBooks cannot be directly accessed, but Kindle devices use it for navigational purposes when jumping to the previous or next section, so it is advised to include one.ĮReading devices vary widely on how the Table of Contents is referenced.
This was meant to replace the EPUB2 NCX, but since eReading adoption of EPUB3 has been so lousy, it is advised to also include an NCX in EPUB3 eBooks for backward compatibility purposes. For EPUB3 eBooks, there is actually a third Table of Contents called the NAV. There are actually two kinds of Tables of Contents required in EPUB2 and MOBI/KF8 eBooks: the HTML Table of Contents and the NCX Table of Contents. Further, for complex eBooks (such as cookbooks, textbooks, etc.) a well-designed Table of Contents will enhance the reading experience and accessibility in ways that a print book cannot. It is usually not necessary for novels to have a Table of Contents inside a print edition, but a Table of Contents is required for all eBooks. The Table of Contents inside an eBook serves two purposes: 1) it gives the reader an idea of how the eBook is structured and 2) it allows the reader to quickly access specific parts of the eBook.
