The purpose of the class yathesis is to facilitate dissertations’ typesetting of theses prepared in France, whatever disciplines and institutes. It implements most notably recommendations from the Ministry of Higher Education and Research and this, transparently to the user. It has also been designed to (optionally) take advantage
of powerful tools available in LaTeX, including packages:
biblatex for the bibliography ;
glossaries for the glossary, list of acronyms and symbols list.
The yathesis class, based on the book class, aims to be both simple to use and, to some extent, (easily) customizable.
The biblatex-chicago package implements the citation style of the Chicago Manual of Style, 16th edition. In this example, the notes option causes biblatex's autocite command to put citations in footnotes. The package can also produce inline author-year citations in the Chicago style. See the package documentation for more information.
The natbib package provides automatic numbering, sorting and formatting of in text citations and bibliographic references in LaTeX. It supports both numeric and author-year citation styles.
The natbib package is the most commonly used package for handling references in LaTeX, and it is very functional, but the more modern biblatex package is also worth a look.
