How to get rid of reference in beamer presentation menu

The following code causes the text References in the top left hand side of the slide. I've tried lots and lots of things but I don't seem to be able to get rid of the text. (Redefining \bibname doesn't work, and using the option title={} for the \printbibliography command also doesn't work.)

(Oddly enough, when I use the same code for the block with the beamer-poster package, using the option name={\hbox to 1mm{}} does get rid of the text. Other names don't....)

\documentclass{beamer}
\usetheme{Berlin}

\usepackage{biblatex}
\begin{document}
\begin{frame}
Some citation~\cite{Knuth:1990}.
\begin{block}{Bibliography}
\printbibliography[name={}]
\end{block}
\end{frame}
\end{document}


The following is the BibTeX file, which should be called tiny.bib.

@Book{Knuth:1990,
author    = {Knuth, Donald E.},
title     = {The {\TeX}book},
keywords  = {latex},
year      = {1990},
isbn      = {0-201-13447-0},
}

With \addbibresource, one should not omit the file extension (normally, .bib). –  lockstep Jan 25 '12 at 16:21
@lockstep Thanks. I didn't know this. It has always worked for me. –  Marc van Dongen Jan 25 '12 at 16:43

In the optional argument of \printbibliography, replace name={} with heading=none.

\documentclass{beamer}
\usetheme{Berlin}

\usepackage{biblatex}

\usepackage{filecontents}

\begin{filecontents}{\jobname.bib}
@Book{Knuth:1990,
author    = {Knuth, Donald E.},
title     = {The {\TeX}book},
keywords  = {latex},
year      = {1990},
isbn      = {0-201-13447-0},
}
\end{filecontents}

\begin{document}
\begin{frame}
Some citation~\cite{Knuth:1990}.
\begin{block}{Bibliography}
\end{block}
\end{frame}
\end{document}


(Note: The filecontents package/environment makes life easier for potential answerers.)

Thanks for the answer and the comment about the filecontents package. –  Marc van Dongen Jan 25 '12 at 16:16

I spent lot of time to find out how to solve exactly this issue, when bibtex command \bibliography{biblio} is used (LyX produces this construct by default).

At the end this solution worked:

\renewcommand{\bibsection}{\subsubsection*{\bibname }}

Welcome to TeX.sx! A tip: If you indent lines by 4 spaces or enclose words in backticks `, they'll be marked as code, as can be seen in my edit. You can also highlight the code and click the "code" button (with "{}" on it). –  doncherry May 17 '12 at 18:05
