Suppressing margin citations in tufte-book

Question

I'm writing a book in tufte-book, in which bibliographic citations (\cite{}) are rendered small in the adjacent page margin and alphabetically at normal size in the bibliography. This is a lovely, elegant and very readable style.

However, the last section of each chapter is on bibliographic and historical discussions in which every paragraph may have 10 or more citations. This is simply too many to appear in the margins. Hence I would like to use a traditional (natbib?) or other citation style just for those final chapter sections. The citation information should appear in the text body as: "... as has been discussed before (Jones and Smith, 2016)" and the Jones and Smith reference appear with all the entries in the bibliographic listing at the end of the book.

The ideal would be to create a new citation call:

\nomargincite{}

or

\cite2{}

that I would use just in those final chapter sections.

Alternatively, perhaps there is a way to create an environment such as:

\begin{nomargincite}

\end{nomargincite}

which would envelope just the text in those final sections.

I've seen reference to changing citation style throughout a tufte-book, but I need to employ two citation styles.

Minimum working example:

\documentclass[twoside,symmetric]{tufte-book}

\begin{document}

\chapter{My first chapter}

Beginning chapter text\cite{Rodgers:16}

\section{Bibliographic remarks}

As has been discussed by many folk (\cite{JonesSmith:18}).

\bibliography{Art}  
\bibliographystyle{plainnat} 

\end{document}

Answer 1

Here is a cheap solution: Use \citep. The tufte classes redefine \cite to give sidenote citations, but they don't define natbib's commands \citet and \citep.

So \citep works a treat and even gives parentheses if you pass the round option to natbib.

\PassOptionsToPackage{round}{natbib}
\documentclass[twoside,symmetric]{tufte-book}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@book{appleby,
  author    = {Humphrey Appleby},
  title     = {On the Importance of the Civil Service},
  year      = {1980},
  publisher = {Pub},
  address   = {Place},
}
\end{filecontents}

\begin{document}

\chapter{My first chapter}

Beginning chapter text\cite{appleby}

\section{Bibliographic remarks}
As has been discussed by many folk \citep{appleby}.


\bibliography{\jobname}  
\bibliographystyle{plainnat} 
\end{document}

Note that this only works if you use an natbib-author-year compatible style (as plainnat is one). It does in particular not work with the provided tufte.bst.
