# Distributing bibliographies to sections — without duplication, and using chapterbib

Currently I use the chapterbib package, together with natbib with option "numbers", and this for a grant-proposal document with a CV-section and a Case-section. Each of these two chapters needs a bibliography at its end (thus using chapterbib), but due to page-restrictions the second bibliography should just continue the first one, not duplicating the entries from the first one.

This is in principal the same question as asked in Bibliography sections without duplicate entries and it has even the same motivation, as discussed there in the comments to the second answer. Similarly we have Multiple reference lists using biblatex: how to remove duplicated entries? again using refsegment.

However my question is whether this can be achieved by the nice machinery of chapterbib? Then I (and others) needed not to change the whole setting. Best would be just to add something to the second include-file, which removes the duplicated entries, and lets the ref-count continue where the first bibliography stops. (So that in effect we have one bibliography, with continuous citation-numbers, only split into two parts.)

It seems that this is actually not possible with chapterbib, but perhaps there is a hack?

If there is no such hack, then perhaps the easiest thing is to initially just use a single bibliography for the whole document, and once everything is finished, then manually take the thebiblibiography-items, find the splitting point, and partition them into two parts.

To be specific, the code structure is as follows:

Main.tex:

\documentclass[twocolumn,11pt]{article}
\usepackage[numbers]{natbib}
\usepackage{chapterbib}
\usepackage{savetrees}

\begin{document}
\onecolumn
\title{Grant Proposal}
\maketitle
\thispagestyle{empty}
{\large
\tableofcontents
}
\newpage

\setlength{\textwidth}{14.8cm}
\include{Part1}
\newpage
\include{Part2}

\end{document}


Part1.tex:

\twocolumn
\setcounter{page}{1}
\section{Track Record}
{\small
\bibliographystyle{plainnat}
\bibliography{Bibfile}
}


Part2.tex:

\section{Research Proposal}
\bibliographystyle{plainnat}
\bibliography{Bibfile}

• I think the approach you outline should work. You would have to manually adjust the numbering of the second bibliography though. This is addressed here: tex.stackexchange.com/questions/289457/… – Michael Palmer Oct 22 '17 at 20:21
• Welcome to TeX.SX! Can you add a small example to play with? – egreg Oct 22 '17 at 20:22
• I just added the outline structure. Hope that helps. – Oliver Kullmann Oct 22 '17 at 20:54
