Subtitle in tufte-book

Question

I would like to add a book subtitle to a tufte-book. Alas, I've tried several methods to add a subtitle, such as those based on the package titling, but all disrupt the font, layout, author name, and so on.

My preference is to have the subtitle in the same font and style as the default in tufte-book, also left-justified, but just one or two font sizes smaller.

The addition of a subtitle must not disrupt the assignment of the title itself, which will appear in headers, footers, and other places throughout my book.

I'm using TeXShop on a Mac.

Here is minimal example:

\documentclass{tufte-book} 

\title{Pixels and Paintings} 

% \title{Pixels and Paintings:  {\Huge Computer image analysis in the study of art}} % gives the right appearance on the title page, but erroneously makes the full title this long version, which ruins headers and footers that contain the title

\author{David G.~Stork}  

\publisher{John Wiley \& Sons}  

\begin{document}

\frontmatter

\maketitle  

\cleardoublepage

\chapter{My first chapter} 

\lipsum[5]

\end{document}

This is what I'd like the title page to look like:

The problem, though, is that anywhere the title is re-used (e.g., in headers and footers) I get the FULL title (which includes the subtitle), all too long and with mixed font sizes and such. All I want in these calls is the TITLE (not the subtitle).

A bit late to the party but this works for me:

\documentclass{tufte-book} 

\makeatletter
\newcommand{\plainsubtitle}{}%     plain-text-only subtitle
\newcommand{\subtitle}[1]{%
  \gdef\@subtitle{#1}%
  \renewcommand{\plainsubtitle}{#1}% use provided plain-text title
  \ifthenelse{\isundefined{\hypersetup}}%
    {}% hyperref is not loaded; do nothing
    {\hypersetup{pdftitle={\plaintitle: \plainsubtitle{}}}}% set the PDF metadata title
}
\renewcommand{\maketitlepage}[0]{%
  \cleardoublepage%
  {%
  \sffamily%
  \begin{fullwidth}%
  \fontsize{18}{20}\selectfont\par\noindent\textcolor{darkgray}{\allcaps{\thanklessauthor}}%
  \vspace{11.5pc}%
  \fontsize{36}{40}\selectfont\par\noindent\textcolor{darkgray}{\allcaps{\thanklesstitle}}%
  \vspace{5pc}%
  \fontsize{24}{28}\selectfont\par\noindent\textcolor{darkgray}{\allcaps{\plainsubtitle}}%
  \vfill%
  \fontsize{14}{16}\selectfont\par\noindent\allcaps{\thanklesspublisher}%
  \end{fullwidth}%
  }
  \thispagestyle{empty}%
  \clearpage%
}
\makeatother

\usepackage{lipsum}

\title{Pixels and Paintings} 
\subtitle{Computer image analysis in the study of art}

\author{David G.~Stork}  

\publisher{John Wiley \& Sons}  

\begin{document}

\frontmatter

\maketitle  

\cleardoublepage

\chapter{My first chapter} 

\lipsum[5]

\end{document}

Answer 2

I just looked into the code of tufte-book. It does not define an command \subtitle which would be perfect for your issue.

I did not find how the title is included in header/footer. Perhaps you can change your given MWE to create such an header/footer including title.

I would try simply a little hack. Define your title as you need it, for example your

\title{Pixels and Paintings:  {\Huge Computer image analysis in the study of art}}

Please see, that there are some warnings comming from \Huge I guess.

After building the titlepage with command \maketitle just change command \title to the short version:

\title{Pixels and Paintings:}

So with the following complete code

\documentclass{tufte-book} 

\usepackage{lipsum}

%\title{Pixels and Paintings} 
\title{Pixels and Paintings:  {\Huge Computer image analysis in the study of art}} % gives the right appearance on the title page, but erroneously makes the full title this long version, which ruins headers and footers that contain the title

\author{David G.~Stork}  

\publisher{John Wiley \& Sons}  

\begin{document}

\frontmatter

\maketitle  

\title{Pixels and Paintings} % <========================================
\cleardoublepage

\chapter{My first chapter} 

\lipsum[1-20]

\end{document}

I get the resulting title:

and no distrurbing titles in header/footer (I do not see any header/footer with your given code). Please test if this workaround is okay for you.
