# Introduction

I have a TeX file that contains a number of references built using TeXStudio on Windows 10 using TeXLive as a backend. Since migrating from BibTeX to BibLaTeX/Biber I haven't been able to access my centralized library.bib file located in $TEXMFLOCAL. I previously used standard BibTeX to retireve references stored in a centralized/database bibliography created by Mendeley in the BibTeX format. This library is located at $TEXMFLOCAL/bibtex/bib/local/library.bib (which translates to D:\Dev\texlive\texmf-local\bibtex\bib\local\library.bib on my system)

## Current Software

• Mendeley 1.16
• TeXLive 2015
• TeXStudio 2.10.8

## Compile Sequence

pdfLatex -> BibTeX/Biber (as appropriate) -> pdfLatex -> pdfLatex

Whilst debugging this problem, I have also been clearing the auxiliary files and compiling from scratch to eliminate any potential issues with corrupt files.

# BibTeX MWE

With BibTeX, I can access this library using:

\documentclass[10pt,a4paper,final]{article}
\usepackage{lipsum} % just for MWE

\begin{document}
\section{Some Title}
\lipsum[2]
\section{Another Title}
\lipsum[2]
\par Summarised point \cite{TheRef2016}
\bibliographystyle{unsrt}
\bibliography{library}
\end{document}


# BibLaTeX MWE (BibTeX Backend)

This example functions as inteded by still uses BibTeX as the backend.

\documentclass{article}
\usepackage{lipsum} % just for MWE
\usepackage[backend=bibtex]{biblatex}
\addbibresource{library.bib}

\begin{document}
\section{Some Title}
\lipsum[2]
\section{Another Title}
\lipsum[2]
\par Some text here \cite{TheRef2016}
\printbibliography
\end{document}


# BibLaTeX MWE (Biber backend)

A .bib file located in the same directory works fine as demonstrated by the MWE on the wiki (MWEB (for BibLaTeX) - Tex.SE Wiki).

However, adjusting it to use the centralized bibliography as before results in an error message saying that the bibliography file cannot be found.

\documentclass{article}
\usepackage{lipsum} % just for MWE
\usepackage[backend=biber]{biblatex}
\addbibresource{library.bib} % Also tried with \bibliography{library.bib}

\begin{document}
\section{Some Title}
\lipsum[2]
\section{Another Title}
\lipsum[2]
\par Some reference \cite{TheRef2016}
\printbibliography
\end{document}


These are the error messages given when compiling with Biber:

INFO - Looking for bibtex format file 'library.bib' for section 0
ERROR - Cannot find 'library.bib'!


# Conclusion

I'm probably missing something fundamental but have been stumped by this problem for the past couple of hours with no luck in finding a solution.

Thanks in advance.

• I wonder what would happen if you moved the file up one directory. – jon Mar 23 '16 at 6:09
• Does it also happen, if you run the commands from the command line? – Tim Hoffmann Mar 23 '16 at 21:20
• @jon - Moving it up one directory didn't solve the issue. @TimHoffmann - Running it from the command line also results in the file not found message. Currently the only work around I am using is to explicitly declare Biber's --input-directory parameter as --input-directory=D:\Dev\texlive\texmf-local\bibtex\bib\local. Which seems counterproductive as this is on the standard BibTex search path. – samthecodingman Mar 25 '16 at 0:24
• How odd. Wish I had a good hint, but I'm on Linux. Last time I used LaTeX on Windows (on my own machine) Biber was not yet invented.... – jon Mar 25 '16 at 1:09
