This question is similar to this question though I can't figure out how to modify the code to suit my purpose. I have the following:
\begin{filecontents*}{\jobname.bib}
@book{Doe2013,
title = {Title I},
author = {Doe, John},
publisher = {Void},
year = {2013}
}
@book{Doe2014,
title = {Title II},
author = {Doe, John},
publisher = {Void},
year = {2014}
}
@book{Doe2015,
title = {Title III},
author = {Doe, John},
publisher = {Void},
year = {2015}
}
\end{filecontents*}
\documentclass{article}
\usepackage{multibib}
\newcites{ll}{Subsection of A}
\usepackage{xcolor}
\usepackage{hyperref}
\hypersetup{
colorlinks = true,
linkbordercolor = {white},
allcolors=cyan
}
\usepackage{etoolbox}
\makeatletter
\patchcmd{\thebibliography}{%
\chapter*{\bibname}\@mkboth{\MakeUppercase\bibname}{\MakeUppercase\bibname}}{%
\section{References}}{}{}
\makeatother
\usepackage[authoryear,sort,round]{natbib}
\renewcommand\refname{Bibliography}
\renewcommand{\bibsection}{\section{\bibname}}
\begin{document}
\section{PART A}
A reference to \citell{Doe2013} and \citepll{Doe2014}, and another to \citep{Doe2015}.
\bibliographystylell{plainnat}
\bibliographyll{BibProb}
\section{PART B}
Same reference to \citell{Doe2013}, but also to \cite{Doe2015}.
\renewcommand{\refname}{Bibliography}
\bibliographystyle{plainnat}
\bibliography{BibProb}
\end{document}
I would like to have the first bibliography "2 Subsection of A" numbered as 1.1, that is, as a subsection of "1 PART A."
