BibTeX, biblatex and biber ⇒ Centering "References" line using natbib

[jjh]

Hello,

For an MA thesis I have to center the word "References" in the References section of my document. Right now I am using natbib with the following option:

\usepackage[sectionbib]{natbib}

This makes the word "References" into a section heading. I have tried to adjust the '\bibsection' command in the natbib style file, but have had no luck getting that particular section heading centered. Any suggestions?

Thank you.
