Hi Bob,

Many thanks for your help.

No, I did not -- my knowledge of the stylesheets is limited and I
didn't know what to try next.

With the customisation, per your advice, I managed to have chapters on
auto and the footers rendered correctly.

When I attempted to do the same for all book parts, however, I
encountered another problem:

- My book has parts and my first part falls on an odd page (left).

- The first part is just a single page, and the second page in the
book is the first page of the first chapter. It falls on an even page
(right).

- The initial.page.number template will return 1 for the first page of
the first part because it's the first page of the book (the front
matter uses roman numerals)

- The footer of the second page (even) will be rendered using the odd
layout. (And, from then on, all the pages will have the footer layouts
reversed.)

I hope that was clear, but I'll be happy to send you the PDF extract
or generate a standalone example that replicated the problem.

I've found that if I override the initial.page.number template to
return 'auto' for parts, the footers get rendered correctly (but the
numbering is not reset, of course).

It looks as if the assumption somewhere is that the first book page
will always be on an odd page. Is that correct?
