How to create a fake ToC on a title page?

Question

I wrote a large book of 2000 pages, so I have to split it into 4 or 5 volumes of about 500 pages (250 paper sheets), for printing and paper binding issues. Each volume would have its own front title page, designed from the code below. It would be usefull to add a Partial Table of Content on it (the true and complete ToC is inside the first volume of the book). Of course, each page number would be added by hand to these "fake ToC", since the title pages are done separately from the main document. I would list only the chapters in these fake partial ToC, since they'll be shown on a single page.

So how would you suggest to build such "partial fake ToC", with the code below, in place of the dumb text part?

Answer 1

This solution is based on the package etoc, with a two-step workflow.

I prepared a mock-up of a book with almost 2000 numbered pages to get a significant TOC. The book has four parts with three chapters each.

I have defined the command \fakeTOC that adds an entry in the table of contents as it were a part. This is needed to later produce the partial TOC by etoc.

The page with the fake TOC is produced with your design using the command \fakeTOC{<part name>} and includes a partial TOC of the part of the full book, as requested.

These added pages will not increase the page counter of the original content! In this way the partial TOCs will have the same page numbers for chapters as in the original document.

The local TOC is built by the etoc package. The layout of this local TOC is, of course, highly customizable. I only added the two horizontal lines.

The main TOC maintains the layout provided by the class.

Initial TOC: Full original document

TOC with fake TOCs: after running generateFkTOC.tex.

Note that the chapter page numbers are the same as in the original table of contents.

Extracted pages with fake TOCs: after running extractfkTOC.tex

As you don't want to have these "fake" pages in your main document, this is the two-step workflow:

(1) Generate them in the main document, adding \fakeTOC{<partnumber>} at the beginning of each part so that the local TOCs are automatically generated and updated by etoc. See generateFkTOC.tex

(2) Extract the four pages generated containing the partial TOCs from the main pdf file, running extractfkTOC.tex

This is generateFkTOC.tex

This is extractfkTOC.tex. Uses the package pdfpages to extract the pages with the fake TOCs to a new pdf file. The page numbers are the number of the physical pages to be extracted from generateFkTOC.tex.

Answer 2

Perhaps something along the lines of having each volume a complete document file. Set the starting page/chapter etc numbers in the preamble of each document based on the last numbers in the preceeding volume to get continuous numbering through the group. Apart from the first volume any ToC will refer only to entries in the volume. For the first volume extend its *.toc file by the *.toc file of the subsequent volumes.

Ok, here's a quick and dirty way of doing what I need:

It isn't ideal, since I need to put back the chapter titles and page numbers by hand, but at least it's doing the job, and it's not too cumbersome to do since I have about 20 chapters, splited into 4 or 5 volumes (so 4 title pages to create like this one). The first volume has the real title page (without a ToC on it!), and the real full ToC inside the volume.
