I am using biblatex and I am trying to put a comma between the author and year.

If I use


the result is

instead of

I have tried the different solutions proposed in this post, but unsuccessfully it didn't work. Maybe the command has been changed since 2013?

How to add a comma between author and year


1 Answer 1


should still work, but nameyeardelim is a context-senstive delimiter now, so you should use


with a current version of biblatex.


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

  • @Kalandrak Do not use both! Just use one of the two: \DeclareDelimFormat{nameyeardelim}{\addcomma\space} with a current version of biblatex and \renewcommand*{\nameyeardelim}{\addcomma\space} for outdated versions of biblatex.

  • @Kalandrak I really can't imagine a legitimate situation where both commands might be needed. So if you have one, I'd be very eager to see it. Can you prepare a short example document/MWE: tex.meta.stackexchange.com/q/228/35864

  • Thank you moewe. I did the change as you suggested, and it is working fine (current version of biblatex).
