# Having multiple tex and bib files for a PhD thesis

I want to use multiple and separate .tex and .bib files for my PhD thesis.

Since some of the .bib files are having same entries (possibly with different reference names), I prefer to force the .tex files uses its own corresponding .bibligraphy to avoid conflict across different bibs. Is there a way to do that INSTEAD of using a single line putting all bibs together : \bibliography{thesis,part1,part2,part3} and I would prefer to keep using bibtex.

MWE

\documentclass[10pt,twoside,openright,english,italian]{book}% twoside!
\usepackage[twoside=true]{geometry}
\usepackaages[...]

\begin{document}
\input{chapters/acknowledge}
\input{chapters/thesis}
\input{chapters/part1}  // in this file there is \bibliography{part1}
\input{chapters/part2}  // in this file there is \bibliography{part2}
\input{chapters/part3}  // in this file there is \bibliography{part3}

\cleardoublepage
\phantomsection
\small
\bibliographystyle{plain}
\bibliography{thesis}  // only for other sections

\end{document}

• With biblatex/biber you could use refsection. – Ulrike Fischer Sep 13 '16 at 9:19
• Except switching to biblatex ? – Amir Sep 13 '16 at 9:55
• It is much easier to do this with Biblatex/Biber. There are options for BibTeX but I don't know if they handle separate .bibs in the way you want. – cfr Sep 13 '16 at 10:23
• You can check the packages for multi bibs: ctan.org/topic/bibtex-multi. But I don't know if one of them can handle separate bibs. – Ulrike Fischer Sep 13 '16 at 10:28
