# Natbib author-year citation style in the tufte-book class

I'm using the tufte-book class and I like it so much!

However, I'd like to have the references in the natbib-way, so that I can use both textual (\citep) and parenthetical (\citep) citations. I have a lot of citations, and I don't want them to take all the room in the page margin (tufte class extensively uses side notes).

All I'd like to have is a working natbib reference style. How can I modify the tufte-common.def file?

The class only redefines the \cite command, you can use \citet and \citep as normal. It works in a document that I have using the package.
