# Change the font of article titles in bibliography

for a school exercise, we need to make changes to the bibliography formatting. The first subtask is to change the font to Arial (don't judge my prof, he's a nice guy actually) for titles of entries of the type @article. We have to use authoryear as the style and \DeclareFieldFormat as the ... command/method. Easy, right? Hells, I've been looking for five hours on this website and in the following documents, but couldn't figure it out. I need to get some fresh air now.

authoryear.bbx standard.bbx biblatex_.def and the biblatex documentation (English and German versions, the English version has the author chapter, which is missing in the German version) and others.

what it should look like:

ok, let me tell you, this is not the correct output (but the task is clear about it the Arial part), as the titles of the publications ("Proposing a new..." and "First-Year Wilkinson...") should be written in Arial. Just imagine they are written in Arial, please. The green year and comic sans pages are part of other subtasks.

The important part here is:

\DeclareFieldFormat[article]{title}
{\fontfamily{Arial}}


This is my code right now:

% -------------
% -------------
\documentclass[10pt,a4paper]{article}

\usepackage[left=3.00cm, right=3.00cm, top=3.00cm, bottom=3.00cm]{geometry}
\usepackage[T1]{fontenc}
\usepackage{gentium}
\usepackage{fontspec}
\setmainfont{GentiumPlus}

\usepackage{xcolor} % gonna need this later

\usepackage[style=authoryear,backend=biber]{biblatex}

% ------------------------------------
% ------------------------------------

% 1. use the authoryear style
% 2. use \DeclareFieldFormat to produce the following adaptations:
% (a) Titles of journal articles are to be written in the Arial font
\DeclareFieldFormat[article]{title}
{\fontfamily{Arial}} % I obviouly have no idea what I'm doing. See output.
% ...
% ... some other task descriptions ...
% ...

\begin{document}

\nocite{*}

% Having the bibliography split up like this is part of a later task for which I stumbled upon the solution while doing another exercise, so it's here already, it doesn't influence the task at hand.

\printbibliography[type=book,title=Books]

\printbibliography[type=article,title=Articles]

\printbibliography[nottype=article,nottype=book,title=Other]

\end{document}

• \fontspec{Arial} maybe? Nov 7 '16 at 15:33
• \setsansfont{Arial} and \DeclareFieldFormat[article]{title}{\sffamily}. Nov 7 '16 at 15:33
• actually, don't loose your head over it. Apparently, I have a {#1} missing somewhere. That's why it doesn't print. But then, I think \fontspec should do the trick, as I am not looking for a fontfamily, but for a specific font. Sorry for the long, buggy question. Nov 7 '16 at 16:58
• I'm voting to close this question as off-topic because the problem is not existing anymore, see the answer by the op Nov 7 '16 at 17:47
• @ScottSeidman Closing is not deleting. Nov 8 '16 at 10:46

I don't know what's the right way to do this, but this question doesn't need an answer any more, as I was asking for something, but the problem was something else. Mods can comment on the correct procedure in such a case.

I just wanted to take this question off the list of unanswered questions and hint to the fact that we found a solution in the comments to the question. I could delete the question, but then again, somebody might be looking for the easiest way to alter the font in a specific part of the bibliography and be persistent throughout the whole file.

The correct to be inserted is as follows:

\DeclareFieldFormat[article]{title}{\fontspec{Arial}{#1}}


where {#1} is a placeholder for the text of the respective field (in this case the title of the article). This was missing in the question, so the code couldn't parse correctly. Additionally, as pointed out in one of the comments by @johannes-b, \fontspec must be used instead of \fontfamily to choose the required font.

PS: Should I check this as community wiki? I don't really understand the purpose of this, yet. Oh and please, definitely don't upvote any of this, as I will see myself bound to delete the whole thing (provided I have the privilege to do so).

• Then put the comment in your answer!! Attribute it if you must. Comments may someday be deleted, answers will not. Nov 7 '16 at 18:27
• Why don't you just include your the correct line \DeclareFieldFormat[article]{title}{\fontspec{Arial}{#1}} in your answer and accept it? It might help other people with the same problem. And since you basically found the answer yourself, that is a very valid option. Nov 7 '16 at 20:30
• No you shouldn't check it as community wiki, and you definitely mustn't delete anything. You can see the upvotes as steps towards more responsibilities on the site if it makes you feel better. Nov 8 '16 at 14:35
• @T.Verron ok, will do. thanks for the feedback. Nov 10 '16 at 8:41
