Thank you both, Abraham and David.
It seems like the least effort now is to produce several PDF files and
concatenate them, which means I also have to manually create a table of
contents. Had I known beforehand that working with different staff sizes
would be such a problem, I simply could have chosen other font sizes, since
those parts don’t actually feature music, only text and chord symbols.
Well, I am wiser for the next project now …

If you can handle the titling (which might differ between
\book and \bookpart) and page numbering, it is trivial to
concatenate the output PDFs with pdftk. Make it more
convenient by suffixing the LP output filenames as shown above
so that you can wildcard/glob them in the command line:

pdftk lilyoutputname*.pdf cat output concatenated-file.pdf

Cheers,
David.

My experience tells me that although the staff-size is larger in the second
\bookpart, the horizontal treatment isn't going to be a normal 17pt. It
will still be more like the 15pt global one. The only way I've found to get
true horizontal spacing correction is with completely different \book
blocks, which you can use a separate #(set-global-staff-size... before each
one, like this:

#(set-global-staff-size 15)
\book {
  \paper {
#(set-global-fonts ...)
  }
  { ... bookpart here ... }
}

#(set-global-staff-size 17)
\book {
  \paper {
#(set-global-fonts ...)
  }
  { ... another bookpart here ... }
}

Unfortunately, this results in separate output PDFs, which I don't think
you want. Now, something I've never fully understood is why each of the
staff-size-setter functions resets the fonts. That's part of the problem
you're seeing. That's also why you'll notice I included a \paper {
#(set-global-fonts ... ) } block in each \book. Personally, I would love to
have this functionality changed.

The only solution I'm aware of that should be able to get you along your
way without changing fonts is to use the \magnifyStaff command, which you
can see its usage in the NR section about Ossia staves:

http://lilypond.org/doc/v2.19/Documentation/notation/modifying-single-staves#ossia-staves

Be aware, though, that it still doesn't correct the horizontal spacing to
be for a true global 17pt staff size, but it might be sufficient for your
needs.

HTH,
Abraham
