About ePub TOC
External TOC vs Internal TOC
External TOC is a feature and advantage of ePub, especially comapring to Mobi. External TOC can be easily accessed everywhere, readers needn't go back to TOC page to switch. Traditionall TOC page is totally unnecessary in ePub.
MS Word can generate internal TOC automatically, but it's useless and even problematic for ePub. We hope user do not use this Word feature. If it already created, please remove it.
ePub Maker from 1.4 will keep internal TOC from Word, only for special use, such as for a further conversion to Amazon Kindle.
TOC List vs TOC Tree
ePub TOC can be a simply list or a complex nested tree. Currently, ePub Maker can only generate TOC list automatically on these considerations,
- Most eReaders' screen size is small, nested TOC can not show properly.
- Most eReaders don't support expanding and closing node, so nested TOC is not easy to browse and operate.
- Nested level is limited or not fully supported by eReaders.
You can edit the toc file (toc.ncx) to rearrange it, i.e. you can nest your items manually, please reference Eidt
ePub Maker can generate TOC automatically if things are arranged properly in Word.
Here's the steps how ePub Maker generate TOC from chapter titles in Word,
- ePub Maker tries extracting the chapter title from the first heading from each split HTML(chapter).
- Extracted chapter titles show in main list ePub Maker, each item can be edited.
- ePub Maker generates TOC from the main list tiems.
TOC List and Chapter Splitting
ePub Maker adopts a simple policy that binds chapter, HTML splitting and TOC llist generation.
TOC structure bases on HTML splitting, that means, each split HTML is an item in TOC. Since HTML splitting bases on section breaks in Word, You can use section breaks in Word to control your TOC itmes in ePub.
Here's a simple table illustrating the structure of ePub TOC on sections in Word and the relations between Word chapter title and ePub TOC items, and listed in ePub TOC, all automatically by ePub Maker.
|Word section||Word heading||ePub HTML filename||ePub TOC item|
|section 3||Chapter I||bookname_3.htm||Chapter I|
|section 4||Chapter II||bookname_4.htm||Chapter II|
|section n||Chapter N||bookname_n.htm||Chapter N|
