# Spaces eaten up in bibliography after location and before colon

I'm very new LaTeX and currently trying to tweak my bibliography to fulfill my needs. This is what it looks like at the moment:

"Frey, Christel: Erfolgsfaktor Vertrauen : Wege zu einer Vertrauenskultur im Unternehmen. 1. Aufl. Wiesbaden: Gabler, 2011. - isbn: 978-3-8349-2539-8."

What I want is a space after the location (goal is: "... Wiesbaden : Gabler ...").

So far I found the "newbibmacro*{institution+location+date}" in the corresponing bbx-file:

\newbibmacro*{institution+location+date}{%
\printlist{location}%
\iflistundef{institution}
\printlist{institution}%
\usebibmacro{date}%
\newunit}


But wherever I added "\space" or s.th. like that didn't change a thing. But nevertheless I am able to insert characters at the desired location. Only spaces are somehow "eaten up".

I'm not sure what you need, so here's some additional information from my tex-file:

\usepackage[ngerman]{babel}
\usepackage[babel,german=guillemets]{csquotes}

• Welcome to TeX.SX! Please don't do that. It is typographically wrong, and you are not even consistent: sometimes you add a space before the colon, sometimes not, like in "isbn:...". – mafp Jun 22 '13 at 9:16
• Thank you for your comment. Unfortunately this decision is out of my hands. My university is following Lorenzen with his format for DIN1505 which demands a space between the location and the following colon in the bibliography -.- So i gotta use the solution that "ach" provided here. – Sascha K0 Jun 22 '13 at 10:29

As mafp said, spaces before colons are typographically questionable. But, if you absolutely must, you can get an extra space. You have to use the literal colon : and not \addcolon, as the latter automatically removes all spaces (since it assumes noone would want an extra space before colon).

As you did not provide an example .bib file I provided one here - but you only need the bits that are marked.

For consistency, I also made it so you get a space before the colon preceding your isbn.

\documentclass{article}
\usepackage[ngerman]{babel}
\usepackage[style=trad-plain, backend=biber, citestyle=authoryear-icomp, bibstyle=authortitle, maxcitenames=1, babel=other]{biblatex}
\usepackage[babel,german=guillemets]{csquotes}

%need to copy from here====>
\renewbibmacro*{publisher+location+date}{%
\printlist{location}%
\iflistundef{publisher}
{\setunit*{\unspace\ :\space}}%
\printlist{publisher}%
\usebibmacro{date}%
\newunit}

\DeclareFieldFormat{isbn}{\mkbibacro{ISBN} :\space #1} %adds space in front of isbn colon
