\chapter{References}
To add coherency to the bibliography and to aid browsing, references are
ordered alphabetically by first author and grouped by major topic:
\begin{description}
\item[-- Vibrations] on page \secpageref{refvib},
\item[-- Levitation] on page \secpageref{reflev},
\item[-- Forces] on page \secpageref{refforce}, and
\item[-- Other] (none of the above) on page \secpageref{refother}.
\end{description}
Some citations fall into more than one category (this very thesis is an
example \cite{robertson2009-thesis}), in which case the reference will appear in
multiple locations in the bibliography; these are conspicuous as their
citation numbers will be out-of-order.
\defbibheading{levitation}{%
\section{Levitation; magnetic and otherwise}%
\seclabel{reflev}}
\defbibheading{forces}{%
\section{Forces between magnets and electromagnets}%
\seclabel{refforce}}
\defbibheading{vibrations}{%
\section{Active and passive vibration}%
\seclabel{refvib}}
\defbibheading{other}{\section{Other}\seclabel{refother}}
% this allows the use of double upright quotes inside bib titles:

\MakeInnerQuote{"}
