eBook Distribution: Understanding Your NCX or eBook Table of Contents

As I perused  the Lulu mailbag this morning I was struck by the number of queries regarding NCX errors in eBook submissions. Some excerpts:

My eBook was recently rejected from retail distribution due to an NCX error. What does that mean? What do I do?

I Googled NCX and was directed to articles on sodium-calcium exchangers? Do I have to know chemistry to make an eBook?

Great questions that unfortunately come as no surprise. NCX errors are among the top three reasons independent eBook authors are rejected from retail distribution. Setting up a fully functional NCX requires some working knowledge of heading styles in MS Word—a feature that a lot of otherwise savvy writers ignore. But never fear, it’s not difficult. And once you’ve applied the proper styles to your document, Lulu’s Epub Converter will convert them into a fully functional NCX for you.

It’s exactly this simple:

  1. Apply Heading 1 style to the Title and to each line containing a Section name (copyright, prologue, etc.) or section (Part 1, Section II, etc.). Heading 1 style will always appear at the top of the next page.
  2. Apply Heading 2 style to each line containing a Chapter name or number
  3. Apply Heading 3 style to each line containing a sub chapter or subsection.

One more thing. I foresee tomorrow’s mailbag asking:

But why?

Do I really need an NCX?

What purpose does it serve?

 

 

So. In a nutshell:

NCX is short for Navigation Control file for XML. (XML is a set of rules for formatting that both humans and computers can read.) It’s that first word in NCX—Navigation—that reveals its purpose. Like a table of contents in a printed book, an NCX helps your readers navigate your work.

But unlike a traditional table of contents, an NCX can’t simply list page numbers. The text in your eBook is scalable (meaning, the size can be changed), and just tilting an iPad 90 degrees can completely change the layout of eBook pages and how many words fit on them. So the number of pages in your eBook is variable from one reader—and even one moment—to the next. A table of contents built on static page numbers is useless, even a little misleading. Navigation has to be connected to something other than page numbers.

Enter the NCX. It contains links to your chapters, sections, and subsections. It lets readers jump from place to place in your eBook without thumbing or scrolling endlessly. You want your readers to have a good experience. So do we, and so do our retail distribution partners. It’s why we collectively urge you to have a fully functional, fully-enjoyable eBook.

EPUBs Made Even Easier with Lulu Ebook Enhancements

Getting your eBook ready for the world to see can be a learning experience – for authors and for Lulu. We always want to give you the best, easiest tools possible to get your eBook out there, and part of reaching that goal is making changes to the process to make it as painless as possible. Case in point: the new multi-file upload and table of contents preview features that help you to make sure you’re well on your way to having a distribution-ready EPUB file.

Making your EPUB file was already pretty easy. You can upload Microsoft DOC and DOCX, RTF, and ODF files, and we’ll take care of converting them into an EPUB for you. For print books you could always upload multiple files and we’d stitch them together into one coherent, print-ready PDF. Now you have the same convenience for your eBook. Maybe you’ve been serializing your work or maybe you’re just taking it one chapter at a time; either way, it’s simple to move forward. Just get  your individual files ready with the first line formatted as Heading 1, upload all of the files and move them around so they’re in the order you want, and you’re done! You’ll have a finished EPUB in no time.

(For more info on our recent enhancements, click on the image above.)

Speaking of those headings, if you’ve ever created an eBook on Lulu you might have received an error message regarding your NCX – the eBook’s table of contents that lets the reader jump instantly to any chapter or section. After all, it’s one of the top ten reasons why eBooks are rejected for retail distribution. Creating a proper NCX requires a pretty straightforward but very specific use of styles and headings so that all of your chapters, sections, and subsections line up appropriately. Not sure if you’ve done yours correctly? After you upload your eBook files you’ll now find a table of contents preview that will let you see how everything will be ordered in your NCX. If you’ve used the method above to upload multiple files for your EPUB, this preview is a simple way to make sure everything was put together just the way you wanted.

You’ve already got the Lulu eBook Creator Guide with all the information you could ever want about eBooks right at your fingertips, and these new additions to the Lulu site will help you out even more along the way. Plus, we still have our great paid services available if you want everything taken care of for you with no hassle. There’s never been a better time to create your eBook, and it’s never been easier to do it with Lulu.
