# Text-citation at start of bibliography entry (BibLaTeX)

I would like to start my bibliography entries with the text-style citation.

I have the bib file mybib.bib

@article{art1,
author = {Foster, Joe and Burton, Nathan and Cook, Andrew},
journal = {Journal 1},
pages = {1-10},
title = {{Title 1}},
volume = {1},
year = {2018}
}


Using \citet{art1} I get Foster et al. (2018), as desired. I would like the formatted reference in the bibliography to start with (Foster et al. (2018)), i.e.,

(Foster et al. (2018)) Joe Foster, Nathan Burton, and Andrew Cook. Title 1. Journal 1, 1:1-10, 2018.

I have tried using the biblatex package in combination with authoryear.

\documentclass{article}
\usepackage[backend=bibtex,natbib=true,style=authoryear,maxcitenames=2,maxbibnames=99,dashed=false,doi,url]{biblatex}
\begin{document}
Citation 1: \citet{art1}
\printbibliography{mybib}
\end{document}


Can somebody help me?

• Have a look at my biblatex-ext style bundle. You'll be interested in introcite, the documentation has a few examples and there are also tex.stackexchange.com/q/433643/35864 and tex.stackexchange.com/q/420595/35864. – moewe Jun 16 '18 at 6:53
• If biblatex-ext works for you, feel free to post an answer with the working code (self-answers are actively encouraged here). If you have problems, just edit your question with what you have tried and why and how it didn't work for you. – moewe Jun 16 '18 at 11:47

introcite from biblatex-ext did the job! See below

\documentclass{article}
\usepackage{csquotes}
\usepackage[backend=bibtex, natbib=true, citestyle=ext-authoryear, bibstyle=ext-authortitle, introcite=plain, maxcitenames=2, maxbibnames=99]{biblatex}

\DeclareNameAlias{sortname}{given-family} % given-family format

\DeclareFieldFormat{bbx@introcite}{\mkbibbold{\mkbibparens{#1}}} % introcite in bold face and between parentheses
\renewcommand*{\introcitepunct}{\addspace} % remove colon between introcite and authors

\begin{document}
\citep{art1}

\citep{art2}

\printbibliography
\end{document}


mybib.bib

@article{art1,
author = {Foster, Joe and Burton, Nathan},
journal = {First journal},
pages = {1-10},
title = {{First Title}},
volume = {1},
number = {10},
month = {1},
year = {2018},
}
@inproceedings{art2,
author = {Foster, Joe and Burton, Nathan and Cook, Andrew},
booktitle = {Proceedings of the 2nd Conference},
pages = {11-20},
title = {{Second Title}},
year = {2018},
month = {12},
}


• I have taken the liberty of adding a picture of the output. Hope you don't mind. – moewe Jun 16 '18 at 15:40
• Note that you may want to add an explicit sorting=nyt to sort your references by name-year-title instead of name-title-year. The sorting is controlled by the .bbx file. authortitle and by extension also ext-authortitle set sorting=nty (or rather don't change the default sorting=nty). But authoryear works better with sorting=nyt. Note also that you can use date = {2017-11} instead of year = {2017}, month = {11}, with biblatex. Furthermore or consider it bad form to double brace title fields for no reason. – moewe Jun 16 '18 at 15:44
