bibliography in Beamer

Question

In Beamer, bibliography is displayed in the way that authors, title and journals are in three lines. Here is an example.

Since I have many references, I am wondering, whether we can put them in one line to save some space? Another option is whether we can split the references into several slides?

Answer 1

For splitting the references up into several slides, use the allowframebreaks option, as in:

\begin{frame}[allowframebreaks]
        \frametitle{References}
        \bibliographystyle{amsalpha}
        \bibliography{../bib_files/jabrefmaster.bib}
\end{frame}

---

For the "three line splitting", this is because you either composed a bibliography list with the \newblock command built-in, or are using a \bibliographystyle that inserts the \newblock command. Your choices are to either drop the \newblocks (either edit them out or using a different style), or modify how beamer handle's the command.

From the link, setting the following in the preamble should work:

\setbeamertemplate{bibliography entry title}{}
\setbeamertemplate{bibliography entry location}{}
\setbeamertemplate{bibliography entry note}{}

Answer 2

Since I encountered the same problem with the 3-line-splitting in a presentation I made recently, I searched the Forum for hours and hours, and nothing I could find worked in my System.

Here, I used

\usepackage[natbib=true,style=authoryear,backend=bibtex,useprefix=true]{biblatex}
\addbibresource{biblio.bib}

in the Preamble, and;

\begin{frame}[allowframebreaks, noframenumbering]
\frametitle{Bibliography}
\printbibliography
\nocite{*}
\end{frame}

inside the Document.

MY SOLUTION to my problems was to turn to a simple, yet effective trick; Colors!

\documentclass[x11names]{beamer}

in the beginning, and I also created a customized command, which I named "biblion", i.e. book, in Greek;

\newcommand{\biblion}[3]{
\bibitem{}  
#1, {\color{black}\textit{#2}}, {\color{LightSteelBlue3}#3} \\
}

and I inserted an indicative section of my Bibliography manually; In the first argument of my command goes the name of the writer, then the title, and, finally, the information about the Publication. It worked wonders for me, therefore, I share it with all of the community!
