I am novice at using Publisher, (as well as book design and layout) but would like to use it to layout/self publish a large (200+ page) book, with multiple chapters TOC, Appendices, index, etc.
When I checked about 6 months ago, I seem to remember that Publisher was not really set up to handle blending multiple input files (such as a Word input file for each chapter) into a cohesive single document. I was planning to use Word for basic text input, then import into Publisher for final formatting, adding graphics, etc.
Some of the features that (I think) Publisher does not have for such a large complex document would include automatic page numbering/updates, etc. (requiring extensive manual effort to update and coordinate something as simple as page numbers after editing changes are made), dedicated page titles for each page within a chapter etc.
If I am wrong about this, please correct me as needed, but it would seem that Publisher does not have some key features that a large book consisting of multiple chapters would require.
I wonder if the developers are moving towards the addition of any of these features?
