# Make a multibib bibliography a subsection rather than a section

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{
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}


Which produces:

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."


\begin{document}
\section{PART A}
A reference to \citell{Doe2013} and \citepll{Doe2014}, and another to \citep{Doe2015}.

\renewcommand{\bibsection}{\subsection{\bibname}}
\bibliographystylell{plainnat}
\bibliographyll{BibProb}

\section{PART B}
Same reference to \citell{Doe2013}, but also to \cite{Doe2015}.

\renewcommand{\bibsection}{\section{\bibname}}
\renewcommand{\refname}{Bibliography}
\bibliographystyle{plainnat}
\bibliography{BibProb}
\end{document}


• That makes sense and works nicely, thanks for the explanation. As a follow up, how could I make the entries in the first bibliography (1.1 Subsection of A) appear as an enumerated list? I mean something like 1. John Doe. Title I. . . . etc., – mdf Jan 29 at 5:15
• I guess something like \makeatletter\renewcommand{\@biblabel}[1]{#1.}\makeatother, though the enumeration is pushed into the margin and does not shift the entire entry to the right. – mdf Jan 29 at 5:57
