I am using the technique to add citations on each page as footnote as given here. It works very nicely, but I would like to tweak it such that at every new chapter it starts labeling the citations from 1 again. At the moment it keeps on numbering the citations one after the other over all the chapters, which means the last chapters have citations all in 3 digits, which look not so nice.
Is there a way to start fresh citations at each chapter?
-Thanks! Here is the code I am using:
\usepackage{manyfoot}
\AtEveryCitekey{\clearfield{title}\clearfield{note}\clearfield{volume}\clearfield{eprint}}
% \usepackage{hyperref}
\hypersetup{%

linkcolor={red!0!black},
citecolor={blue!0!black},
urlcolor={blue!80!black}
}
