[ivoron]

I should have been more specific.

Because I started with the Kindle book (Kindle does not generate a TOC for you) I had to hand-code the TOC and included it within the book file.

Then when I worked on the Mobipocket version of the book I removed the internal TOC coding and used Mobipocket to generate an separate, external TOC file.

I read in Harry T's tutorial that it is better to have an internal TOC. I may have misunderstood the comment, but read it as saying that it is better to have TOC and book in the same file.

I'll go back and reread the tutorial ...
