Biblatex and citation reset between chapters

Question

I have a feeling that there is an obvious answer to this question that I'm somehow managing to miss. However, I've tried most of the commands in the biblatex documentation and I still can't figure it out.

What I want to do is reset the count for my footnotes and citations between chapters. In addition I also want ibid's, opcit's etc to start again at the beginning of a new chapter.

I'm currently using XeLaTeX with biblatex. My preamble is:

\documentclass[12pt,oneside]{book}

\usepackage[protrusion=true,expansion=true]{microtype}
\usepackage[style=verbose-trad1=true,natbib=true,sortcites=true]{biblatex}
\bibliography{bib.bib}

%Additional Stuff that I don't think should influenec the bibliography, but is here just in case
\interfootnotelinepenalty=10000
\usepackage{fontspec}
\usepackage{titlesec}
\defaultfontfeatures{Ligatures=TeX}
\usepackage{sectsty}
\allsectionsfont{\sffamily}
\setmainfont{Lyon Text Regular No. 2}
\setsansfont{Lyon Display Light}
\usepackage[margin=3.5cm]{geometry}
\pretolerance=5000
\tolerance=1000 
\usepackage{setspace}
\usepackage{graphicx}

In the book class, footnotes (including citations as footnotes) are reset at the start of a new chapter by default. If it's different for you, you must be doing something your code snippet doesn't show. You could try to add the following to your document preamble (note that the starred version of \counterwithin doesn't add chapter prefixes):

\usepackage{chngcntr}
\counterwithin*{footnote}{chapter}

To reset "ibid." and similar expressions per chapter, use the biblatex package option citereset=chapter.

\documentclass{report}

\usepackage[style=verbose-trad1,citereset=chapter]{biblatex}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@misc{A01,
  author = {Author, A.},
  year = {2001},
  title = {Alpha},
}
@misc{B02,
  author = {Buthor, B.},
  year = {2002},
  title = {Bravo},
}
@misc{C03,
  author = {Cuthor, C.},
  year = {2003},
  title = {Charlie},
}
\end{filecontents}

\addbibresource{\jobname.bib}

\begin{document}

\chapter{foo}

Some text \autocite{A01}.

Some text \autocite{A01}.

Some text \autocite{B02}.

\chapter{bar}

Some text \autocite{B02}.

Some text \autocite{C03}.

\printbibliography
