Hi there: biblatex-Chicago is producing the following bibliographic entry which is almost exactly the way I need it:
Kleiss, Karen, and Charles Rusnell. 2005a. “Empty seats? No problem –scare up more passengers: Gov’t plans to expand air fleet’s use by running virtual airline service.” Edmonton Journal, Mar. 4, A1[\b].

But I need it to look as follows:
Kleiss, Karen, and Charles Rusnell. 2005a. “Empty seats? No problem –scare up more passengers: Gov’t plans to expand air fleet’s use by running virtual airline service.” Edmonton Journal, 4 March: A1[\b].


The .bib file looks as follows:

Code: Select all

@article{Kleiss:2005ta,
author = {Kleiss, Karen and Rusnell, Charles},
title = {\mkbibquote{Planes fly empty 300 times a year: Government isn't telling whole story of air fleet costs, critics say, noting flights are rarely full and fixed costs are high}},
entrysubtype = {magazine},
journal = {Edmonton Journal},
date = {2005-03-05},
pages = {A17},
}

And the document code looks like this:

Code: Select all

\documentclass[12pt]{article}
\usepackage[authordate]{biblatex-chicago}
\bibliography{/Users/simon/Documents/CPSA_Paper/CPSA_2009/bib_file}
\begin{document}
Some interesting text here \parencite{Kleiss:2005ta}. 
\printbibliography
\end{document}

Thanks, very much!
