Timothy,

Thank you for your response. Your time spent writing out a solution is
greatly appreciate.
I would like to have something that is consistent with the manual.

I find the best way to handle having the opus printed once only on the first
piece of a book is to redefine bookTitleMarkup and scoreTitleMarkup, moving
the opus field to the bookTitleMarkup

\version "2.19.59"

% Move the opus markup from the score title to the % book title so it isn't
repeated for every score.
% Adapted from ly/titling-init.ly

bookopus = \paper {
   bookTitleMarkup = \markup {
     \override #'(baseline-skip . 3.5)
     \column {
       \fill-line { \fromproperty #'header:dedication }
       \override #'(baseline-skip . 3.5)
       \column {
         \fill-line {
           \huge \larger \larger \bold
           \fromproperty #'header:title
         }
         \fill-line {
           \large \bold
           \fromproperty #'header:subtitle
         }
         \fill-line {
           \smaller \bold
           \fromproperty #'header:subsubtitle
         }
         \fill-line {
           \fromproperty #'header:poet
           { \large \bold \fromproperty #'header:instrument }
           \fromproperty #'header:composer
         }
       }
       \override #'(baseline-skip . 2.0)
       \column {
         \null
         \fill-line {
           \null
           \fromproperty #'header:opus
         }
         \fill-line {
           \fromproperty #'header:meter
           \fromproperty #'header:arranger
         }
       }
     }
   }

   scoreTitleMarkup = \markup {
     \column {
       \fill-line {
         \fromproperty #'header:piece
         \null
       }
     }
   }
}

\bookopus

\book {
   \header { title="Title" composer="Composer" opus="opus" }
   \score { c''1 }
   \score { d''1 }
}
