# paracol with marginnote always on the right side

The goal I am trying to ultimately achieve is a document where I have explanation on even pages and corresponding images on the odd pages. Normally, I put figure captions, citations and footnotes into the margin using the tufte-latex package. There, the margin is always on the right.

Is there a way to have the marginnote of of twosided document always on the right, when using paracol?

Here is a MWE where the marginnote is not set into the margin.

\documentclass{tufte-book}

\let\tuftenote=\marginnote
\let\marginnote\relax% make compatible
\RequirePackage{marginnote}

\usepackage{graphicx, paracol, lipsum, showframe}

\begin{document}
\begin{paracol}[1]*{2}
\switchcolumn[1]\section{Introduction}
\switchcolumn[0]*
\switchcolumn[1]
\marginnote{Bar}
\lipsum
\switchcolumn[0]
\marginnote{Figure 1: Foo}%
\noindent\includegraphics[width=\textwidth]{example-grid-100x100pt}
\end{paracol}
\end{document}


This is not a problem with tufte-book, as I can observe the same effect with article.

\documentclass{article}

\usepackage[showframe,
a4paper,
left=24.8mm,
top=27.4mm,
textwidth=107mm,
marginparsep=8.2mm,
marginparwidth=49.4mm,
textheight=55\baselineskip,

\usepackage{graphicx, paracol, marginnote, lipsum}

\begin{document}
\begin{paracol}[1]*{2}
\switchcolumn[1]\section{Introduction}
\switchcolumn[0]*
\switchcolumn[1]
\marginnote{Bar}
\lipsum
\switchcolumn[0]
\marginnote{Figure 1: Foo}%
\noindent\includegraphics[width=\textwidth]{example-grid-100x100pt}
\end{paracol}
\end{document}


Here is the tufte-book version of the MWE.

• So you want paracol to be twosided but the marginpar area to onesided? I suppose you could use the reverse marginpar area on even pages, but you would need foddpage or some equivalent to tell (\ifodd\value{page} is not reliable).. It might be easier to replace the whole marginotes package. – John Kormylo Sep 1 '20 at 13:23
• Yes, see my edit. There is a patch for the marginnotes package, but it does not work in combination with paracol. – Manuel Schmidt Sep 1 '20 at 14:30

This seems to do the trick:

\documentclass{tufte-book}

\let\tuftenote=\marginnote
\let\marginnote\relax% make compatible
\RequirePackage{marginnote}

\usepackage{graphicx, paracol, lipsum, showframe}

\twosided
\reversemarginpar

\begin{document}
\begin{paracol}[1]*{2}
\switchcolumn[1]\section{Introduction}
\switchcolumn[0]*
\switchcolumn[1]
\marginnote{Bar}
\lipsum
\switchcolumn[0]
\marginnote{Figure 1: Foo}%
\noindent\includegraphics[width=\columnwidth]{example-grid-100x100pt}
\end{paracol}
\end{document}
