lilypond book

[Carlos Martinez]

Hi, 

I am trying to put together a book. A collection  of 13 pieces with lilypond. 

I would like the book to be setup in this way 

#(set-global-staff-size 20)

\version "2.20.0"

\paper {
  
  #(set-paper-size "letter")
  top-margin = .50\in
   right-margin = .50\in
   left-margin = .50\in
   bottom-margin =  .50\in
     
   \include "../footer001.ily"
  evenFooterMarkup = \oddFooterMarkup  
  
}




I want each piece to show its own 

- Title and composer
- each piece start in its own page. 

I am trying to setting it up but I cannot do it!

I have already engraved each piece… and would love to have the include. But 
somehow it is not working..

Thanks!

For the 

\bookpart {

  \header { maintainer = "Carlos R Martinez" }
  
  \header {
  
  
  title = ##f
    composer = ##f
  }

  \markup { \fill-line { \center-column
