# Volume Comma Issue Number

I would like to make some amendments for my bib appearances. One of them is changing the article style. This is what it looks like now:

I would like the quotation marks to be removed and the volume and issue number to look like this

This is what the bib entry looks like: 

@article{McMaster.1963,
author = {McMaster, John},
year = {1963},
title = {The Takashima Mine},
pages = {215--239},
pagination = {page},
volume = {38},
subtitle = {British Capital and Japanese Industrialization},
number = {3},
abstract = {}
}


This is what the bibliography looks like:

%----------------------------------------------------------------------------
%   BIB
%----------------------------------------------------------------------------
\usepackage[
backend=biber,
style=authoryear,
sorting=nyvt
]{biblatex}
\renewcommand{\mkbibnamefamily}[1]{\textsc{#1}}
\DeclareFieldFormat{postnote}{#1}
\DeclareFieldFormat{multipostnote}{#1}
\usepackage{url}
\urlstyle{same}


Sorry for these questions, I am rather new to LaTeX and still trying to figure things out

If you use the drop-in replacement ext-authoryear from biblatex-ext, you only need a few more lines.

The punctuation between volume and number is controlled by \volnumdelim. The field format of the title with \DeclareFieldFormat

\documentclass[ngerman]{article}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
\usepackage{babel}
\usepackage{csquotes}

\usepackage[
backend=biber,
style=ext-authoryear,
sorting=nyvt
]{biblatex}

\renewcommand{\mkbibnamefamily}[1]{\textsc{#1}}

\DeclareFieldFormat
[article,inbook,incollection,inproceedings,patent,thesis,unpublished]
{title}{#1\isdot}

\DeclareFieldFormat{postnote}{#1}
\DeclareFieldFormat{multipostnote}{#1}

\usepackage{url}
\urlstyle{same}

\usepackage{filecontents}
\begin{filecontents}{\jobname.bib}
@article{McMaster.1963,
author = {McMaster, John},
year = {1963},
title = {The Takashima Mine},
pages = {215--239},
pagination = {page},
volume = {38},
subtitle = {British Capital and Japanese Industrialization},
number = {3},
abstract = {}
}
\end{filecontents}

\begin{document}
\cite{sigfridsson,McMaster.1963}
\printbibliography
\end{document}


If you can't (or don't want to) use ext-authoryear, the one line with \renewcommand*{\volnumdelim}{\addcomma\space} above needs to be replaced with

\newcommand*{\volnumdelim}{\addcomma\space}

\renewbibmacro*{volume+number+eid}{%
\printfield{volume}%
\setunit*{\volnumdelim}%
\printfield{number}%

of course you could cut out the middle man of \volnumdelim here if you want and can directly write \setunit*{\addcomma\space}% instead.
• @user168390 Overleaf are still using an older version of biblatex and they don't have biblatex-ext` installed. Use the workaround at the end of the answer. – moewe Oct 30 '18 at 19:04
