# Add more space after a dashed rule in biblatex

Following typographic conventions, I'm using a three-em rule in dashed entries in my bibliography. I feel, however, that there is too little space between the rule and the following period.

As the following MWE shows, adding \space has no effect (I've also tried \addspace, \(add)thinspace, and \hspace{}, all without effect. How can I add space after the rule?

\documentclass{article}
\usepackage{filecontents}
\usepackage[style = authoryear, dashed = true]{biblatex}
\begin{filecontents}{\jobname.bib}
@book{smith1965,
AUTHOR = "Ian Smith",
TITLE = "The great book about nothing",
YEAR = "1965"}
@book{smith1972,
AUTHOR = "Ian Smith",
TITLE = "I have more to say about nothing",
YEAR = "1972"}
\end{filecontents}
\begin{document}
\nocite{*}
\printbibliography
\end{document}

• @egreg I often use a style in which the entries are formatted like Smith, Ian. 1965. _Title_. – Sverre Aug 31 '15 at 19:20

As far as I can tell, \addperiod gobbles up preceding glue, so \space before it does nothing. On the other hand, \hspace* tricks it into thinking that no space was there, so I can propose
\renewcommand*\bibnamedash{\rule[0.48ex]{3em}{0.14ex}\hspace*{.2em}\addperiod\space}

Adjust to suit. If I use \hspace*{1em} (exaggerating the effect), I get
