# Shortening margin citations in tufte class

How would one display just the Author and Year of the citation in the margin, while keeping the full citation in the references page?

I've tried to modify a previous suggestion that would display abbreviated citations only after they had be cited once. This unfortunately didn't work -- the reference number appears instead of any citation at all:

This is what they usually look like:

As you can see it gets very busy very quickly. Some pages the margin is all citations!

I've searched everywhere for this and tried editing solutions to similar requests -- alas! No luck. Any help or advice would be greatly appreciated.

Thanks!

Edit: Here's a minimal working example:

\documentclass[a4paper,nofonts,oneside]{tufte-book}
\usepackage{amsfonts, amsmath, amssymb}
\begin{document}

\subsection{Non-equilibrium Spin Mixing}

Spontaneous Magnetization!! \cite{lamport94}

Under the constraint of number and magnetization conservation, there are just two dynamical variables\cite{lamport94}: $\rho_0$, the fractional population of the $m=0$ component, and     relative phase difference $\theta (t)\equiv\theta_+ + \theta_- - 2\theta_0$. $\theta$ can     be thought of as a control for the degree of magnetization.

Under the SMA, the spin-dependent energy functional is given by\cite{lamport94}:

\begin{thebibliography}{9}

\bibitem{lamport94}
Leslie Lamport,
\emph{\LaTeX: A Document Preparation System}.
2nd Edition,
1994.

\end{thebibliography}

\end{document}

Thanks for the link! I've included a minimal working example. – S Chen Sep 6 '13 at 9:41
Your MWE is not compilable... – karlkoeller Sep 6 '13 at 14:50

Your MWE is not compilable, but you can try the following: Use biblatex instead of bibtex. You can find the explanation how to do that here. Then, you can take advantage of biblatex's large set of options. Put

\AtEveryCitekey{\clearfield{title}}


in the preamble to not show the title in the margin. However, the bibliography will still show it.

\AtEveryCitekey{\clearfield{url}}


clears the url as well and so on. Biblatex even allows different citation and bibliography styles. I strongly recommend it with tufte-latex.

I cleared all the fields I could think of, but I still get a margin note citation of the form Author. In: (Year). Any idea how to get rid of the In: and the dots after author and year? – ThomasH Aug 23 '14 at 23:48
