# Author-year citation call-out to be repeated at the start of the formatted bibliographic item

I'm using natbib package and I'd like to have a bibliography where :

• the citation in the text are like : [Kent, 2000] or [Kent and Lane, 2000] or [Kent et al., 2000] (in bold)

• and in the bibliography : [Kent et al., year] Kent, C., Lane, L., Allen, B. (2000). The title of the article. Journal, etc

It is kind of a mix between "apalike" and "alpha" but my biggest problem is to have the brackets in the bibliography. I tried to edit the .bst files or via makebst but I was lost in it and didn't find the place where specify the brackets in the biblio... :-)

I hope it is clear, and someone has an idea ! Thks

• Welcome to TeX.SE. Please elaborate on the use case you have in mind. Are you concerned that your readers are experiencing difficulties associating the string "[Kent, 2000]" (presumably generated with a \citep instruction, right?) in the body of the document with "Kent, C. (2000)..." in the formatted bibliography unless you provide a "[Kent, 2000]" prefix? Similarly, are they having a hard time connecting "[Kent et al., 2000]" in the body of the document with "Kent, C., Lane, L., Allen, B. (2000) ... " in the bibliography unless they're also shown a "[Kent et al., 2000]" prefix? – Mico Nov 24 '16 at 16:10
• BibTeX is rather outdated and its very complicated to realize some things. If ever possible I would suggest switching to BibLaTeX, where most of these things can be done rather easily. – Manuel Weinkauf Nov 24 '16 at 16:18
• I've taken the liberty of editing the title of your posting to clarify its intended objective. (The square-brackets part isn't the crucial message, is it?) Feel free to revert if you disagree. – Mico Nov 24 '16 at 16:18
• @Mico : No problem for the title, thks. I am not concerned that readers won't understand, I just find it more readable this way. Mainly because I have several citations from the same authors. And yes, in the text the \citep command works just fine I'm still discovering latex world and I have already worked with natbib. And I'm using it for the chapterbib option in order to have one bibliography each chapter. – Simon Nov 24 '16 at 16:36

Here a small fix:

\documentclass{article}
\usepackage{natbib}
\usepackage{xpatch}
\makeatletter
\renewcommand\NAT@open{[\bfseries}
\renewcommand\NAT@close{]}
\xpatchcmd\@lbibitem{\item[\hfil\NAT@anchor{#2}{\NAT@num}]}{\item[\citep{#2}\NAT@anchor{#2}{\NAT@num}]}{}{}
\begin{document}
Text \citep{article-full}

Text \citep{book-full}

\bibliographystyle{newapa}
\bibliography{xampl}
\end{document}


The justification of the label is yours ;-)
