# Author year citation without comma

I am relatively new to the natbib package. I was wondering if there is an option to remove the 'comma' between an author name and year. For example, using the style apalike, I get (Name, year), but I want it to appear as (Name year).

• It would be easy to do with biblatex. – Bernard Apr 6 '16 at 17:58
• Even if I think what you want to achieve is rather easy to achieve (see my suggestion below), I would second @Bernard and recommend checking out biblatex. It is so much more powerful and flexible. And given that you are new to natbib, as you say, I would invest in the switch and start reaping the benefits. – Daniel Apr 6 '16 at 20:38
• @Bernard -- "It would be easy to do with biblatex" -- Is the instruction \setcitestyle{aysep={}} not easy enough? :-) – Mico Apr 6 '16 at 20:52
• @ Mico: Sure, but I couldn't make such an naswer knowing not natbib. I meant it's easier to customise biblatex than to put hands on a .bst file. – Bernard Apr 6 '16 at 20:56
• @Bernard - The OP did mention the use of the natbib package. The form of the citation call-out -- including the presence or absence of a comma between the author and year labels -- is controlled by natbib, not the bst file. – Mico Apr 6 '16 at 20:59

The natbibpackage provides the command \setcitestyle that allows for some customization. The delimiter between author and year in citations is set using the key-value pair aysep={<char>}.

Here is an almost MWE (fill in your bib file and a prober cite key):

\documentclass[]{article}
\usepackage{natbib}
\setcitestyle{aysep={}}
\begin{document}
\bibliographystyle{apalike}

\citep{<some cite key in your bib file>}

\bibliography{<bib file>}
\end{document}
