# Customizing citations and the list of publications depending on the author

Say I use a bibliography file in my document, relying on Biblatex and Biber for citation management.

Given a citation command such as \cite{A, B, C} (or any other standard Biblatex citation command), I'd like the resulting citations to be typeset differently depending on whether a given field (e.g. the author field) in the corresponding bibliography entry contains a given string (e.g. someone's lastname).

Besides, I'd like to generate two different bibliography sections in the resulting document, depending on the same condition as above.

Typically this would be used to differentiate, both at the citation level in the main text and in the appendix, the publications that I co-authored from others.

EDIT: adding a MWE:

\documentclass{article}
\usepackage{filecontents}
\usepackage[backend=biber,style = alphabetic]{biblatex}
\DeclareSourcemap{%
\maps[datatype=bibtex]{%
\map{%
\step[fieldsource=author, match=Doe, final]%
\step[fieldset=keywords, fieldvalue=doe]%
}%
}%
}
\begin{filecontents}{\jobname.bib}
@Book{p1,
author =       "A. U. Thor and John Doe",
title =        "A Scientific Article 1",
year =         "1975"
}
@Book{p2,
author =       "John Doe",
title =        "A Scientific Article 2",
year =         "1985"
}
@Book{p3,
author =       "Joe Bar",
title =        "A Scientific Article 3",
year =         "1995"
}
@Book{p4,
author =       "Jane Baz",
title =        "A Scientific Article 4",
year =         "2005"
}
\end{filecontents}
\begin{document}
% Requirement 1: should make citations of Doe bold
In \parencite{p4, p1, p2, p3}, TD75'' and Doe85'' should appear in
bold (the semicolon should remain plain).

% Requirement 2: separating bibliographies. IT WORKS.

• How differently would you like them to be typeset? And would you also be OK using the keyword field instead of auto-detection of names? Anyway, biblatex: filter out publications from a specific author in the references dynamically seems to be a pretty good fit (there you can even get automatic name recognition). – moewe Jan 7 '16 at 17:46
• @moewe Say in bold or emphasized, perhaps with a different color. Thanks for the link, I had overlooked this one but it indeed works. So a good half of my requirements are met :-) – Grayswandyr Jan 8 '16 at 8:08
• OK. The change required for that will heavily depend on the style you use. (It is probably necessary to change the cite bibmacro, though with some styles there might be other solutions.) So in order to be of any help we would need to see which one you use, this is best done in an MWE. – moewe Jan 8 '16 at 8:53

With the solution from biblatex: separating publications of a specific author in the bibliography that sets the keywords you only need

\DeclareFieldFormat{prefixnumber}{\ifkeyword{doe}{\mkbibbold{#1}}{#1}}
\DeclareFieldFormat{labelalpha}{\ifkeyword{doe}{\mkbibbold{#1}}{#1}}
\DeclareFieldFormat{extraalpha}{\ifkeyword{doe}{\mkbibbold{#1}}{#1}}


to get what you want.

Just because it is fancy to use name hashes, here is a version of Audrey's answer to biblatex: filter out publications from a specific author in the references dynamically.

You can find the name hash you need to use in the .bbl file (as described in more detail in Highlight an author in bibliography using biblatex allowing bibliography style to format it).

This solution uses categories instead of keywords so we have to adjust the code a bit, but the basic idea is the same.

\documentclass{article}
\usepackage{filecontents}
\usepackage[backend=biber,style = alphabetic]{biblatex}
\begin{filecontents}{\jobname.bib}
@Book{p1,
author =       "A. U. Thor and John Doe",
title =        "A Scientific Article 1",
year =         "1975"
}
@Book{p2,
author =       "John Doe",
title =        "A Scientific Article 2",
year =         "1985"
}
@Book{p3,
author =       "Joe Bar",
title =        "A Scientific Article 3",
year =         "1995"
}
@Book{p4,
author =       "Jane Baz",
title =        "A Scientific Article 4",
year =         "2005"
}
\end{filecontents}

• @Grayswandyr You could wrap the \DeclareFieldFormat in \AtEveryCite: \AtEveryCite{% \DeclareFieldFormat{prefixnumber}{\ifkeyword{doe}{\mkbibbold{#1}}{#1}}% \DeclareFieldFormat{labelalpha}{\ifkeyword{doe}{\mkbibbold{#1}}{#1}}% \DeclareFieldFormat{extraalpha}{\ifkeyword{doe}{\mkbibbold{#1}}{#1}}} (modulo line breaks). – moewe Jan 11 '16 at 9:59
• Citations are indeed bold when citestyle = alphabetic but I can't find a way to achieve the same result with, say, citestyle = authoryear-comp-brackets. Does anyone know a way to do this? – Grayswandyr Jul 26 '16 at 9:42
• @Grayswandyr I don't know the style authoryear-comp-brackets, but the name suggests it is derived from authoryear so a solution would have to be quite different (not necessarily more complicated) than what we used for alphabetic. If you need help for that I suggest you ask a new question (you can link back to this one here if you like). If you decide to ask a new question, make sure to include additionally to the MWE the information where we can find authoryear-comp-brackets as this is not a standard style. – moewe Jul 26 '16 at 14:40
