# Getting rid of period and comma

I am using apa.bst and want to know how to:

1) Get rid of the period after the year; and 2) Get rid of the comma after the journal title.

I currently have: Baba, SA (1997). Democracies and inefficiency. Economics and Politics, 9(2):99–114.

I need it to be: Baba, SA (1997) Democracies and inefficiency. Economics and Politics 9(2):99–114.

You can use biblatex and more specifically biblatex-apa, as it is easy to customise. Here is an example where you'll find the lines of code to add to your preamble. Note that the syntax to produce a bibliography is somewhat different with biblatex:

\documentclass[12pt,american, a4paper]{article}
\usepackage[utf8]{inputenc}
\usepackage[T1]{fontenc}

\usepackage{babel}
\usepackage{csquotes}

\usepackage[style=apa, backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}

\begin{filecontents}{ashortone.bib}
@article{DroitVolet2007,
author = {Droit-Volet, S. and Meck, W. H.},
year = {2007},
title = {{H}ow emotions colour our perception of time},
pages = {504--513},
volume = {11},
number = {12},
journal = {Trends in Cognitive Sciences}
}
\end{filecontents}

\usepackage{xpatch}
\xpatchbibmacro{journal+issuetitle}{%
\usebibmacro{journal}%
}
{%
\usebibmacro{journal}%
}{}{}
