No - I think that's perfect. Thanks much - I didn't find a procedure for 
"just printing" a book.

What I was trying to achieve here: I have a document with theory 
exercises which come in several guises - figured bass, figured bass with 
given melody, only bass and melody, and so on -, richly adorned with 
\tag'ging. Since there are various chapters/sections, interspersed texts 
etc., they do not fit into one \score.

I wanted to have a convenient way to generate all various combinations; 
hence a function that receives a filename suffix and (omitted in my 
examples) a list of tags that should be removed.

The book now is defined using

create = #(define-void-function (omitTags suffix) (list? string?) 
(print-book-with-defaults #{
 \book {
    \bookOutputSuffix #suffix
     ...
  } #}))

and each story contains a \removeWithTag #omitTags. Hence by just issuing

\create #'() "complete"
\create #'(middleVoices bcFigures) "OuterVoices"
\create #'(upperVoices) "bc"
\create #'(upperVoices bcFigures) "BassOnly"

I get four files with completely different versions of a whole book 
containing multiple \score's and interspersed \markup's.

Works like a charm now - thanks much!

Best
