I have this problem: it seems that beamer did not read the bibtex file. Below is the syntax that I am using:


\usepackage{natbib} %citep and citet
\renewcommand{\bibsection}{\subsubsection*{\bibname}} % to avoid References creates new section/subsection in header


\def\newblock{\hskip .11em plus .33em minus .07em}
\bibliography{reff.bib} % file name of the bibtex

You can use four spaces at the beginning of a line tho mark the line as code (or highlight a block of code and use the 101010-button). Please also include newlines at the appropriate places to make the code readable. – Caramdir Dec 2 '10 at 4:43
which beginning of a line did you mean? – ssaee Dec 2 '10 at 5:26
Well, you've not got any citations so you won't get any bibliography, beamer or not. – Joseph Wright Dec 2 '10 at 8:10

Try to add


in your document for testing.

Then you should get a bibliography, which includes your complete bib file items. In a real beamer document you can use \cite commands or more specific forms of \nocite instead, of course.

You have to insert the bibliography without the .bib extension, therefore as

\bibliography{reff} % file name of the bibtex
