Iintensive search has not yield any answer, but I still suspect this might be a double-post:

Instead of a question mark, I want to have the cite-key if the reference was not found in the bib file. Is there an easy package / command for this?

So far, I'm using natbib and my bibliography style is chicago (if it matters).

/edit In my header, I have

\usepackage[round]{natbib} 
\bibliographystyle{chicago}

  • If the entry does not exist, or if BibTeX was not run, question marks would appear. Instead of those question marks, you want do have the bibkey? Did i understand this correctly? – Johannes_B Apr 01 '14 at 08:04

biblatex does this by default, and the biblatex-chicago package provides several different Chicago styles, see the manual. Note that the default backend for biblatex is biber, not bibtex, so the compilation sequence is

pdflatex file.tex
biber file.bcf
pdflatex file.tex

The bibkeys are also displayed before running biber and pdflatex the second time, whenever you'd get question marks with natbib/bibtex.

When switching from natbib to biblatex-chicago you need to make several changes in your document:

  • Replace \usepackage[round]{natbib} \bibliographystyle{chicago} in the preamble with

    \usepackage[authordate]{biblatex-chicago}
\addbibresource{nameofyourbibfile.bib}

  • Replace \bibliography{nameofyourbibfile} in your document with \printbibliography.

  • Replace \citet with \textcite and \citep with \parencite. Use Find&replace in your editor to do this.

(Normally with plain biblatex you could have added natbib=true to the package options which would have made \citet and \citep available, but biblatex-chicago does not define this.)

Some questions with more information about biblatex:

Here is a short example:

\documentclass{article}
\usepackage[T1]{fontenc}
\usepackage[authordate]{biblatex-chicago}
\addbibresource{biblatex-examples.bib}
\begin{document}
\textcite{aksin}

\textcite{notavailable}

\printbibliography
\end{document}

  • Thanks. Is there a way to integrate this the way I'm calling chicago? (see edit). I'd be afraid unknown side effects depending on the way I call it.. – FooBar Apr 01 '14 at 09:24
  • @FooBar No, you can't. biblatex and natbib are completely different systems, and \bibliographystyle won't work with the former. I don't know exactly how that bibliographystyle looks, but biblatex-chicago should have implemented the style defined by the Chicago Manual of Style. I'll update my answer in a bit, with some more info. – Torbjørn T. Apr 01 '14 at 09:34
