I know the thread Set limit to one author when using “et al.” in biblatex but this thread is about BibTeX.

Code where bibliography in BibTeX

\documentclass{beamer}

\setbeamertemplate{bibliography item}{\insertbiblabel} % I think not necessary

\begin{document}
\begin{frame}
\frametitle{Cesarean Section and Epidemiology}

\begin{itemize}
\item First Modern C-section by Ferdinand Adolf Kehrer 1881. \cite{history_c_section}
\item Surgical procedure where one or more incisions are made through a mother's abdomen and uterus to deliver one or more babies.
\item 2012, 23M globally. \cite{molina} 10-15\% of all. \cite{who_c_section} but >19\% better? 
\end{itemize}

\bibliographystyle{IEEEtranN}
\bibliography{task}

\end{frame}

Task.bib

@book{ history_c_section,
  author = "Dadebo, Dr. Benjamin",
  year = 2012,
  title = "Begat By God: Understanding the Concept of Being Born Again",
  publisher = "Xlibris Corporation",
  pages = "31–",
  note = "ISBN 978-1-4771-0612-9"
}

@article{ who_c_section,
  author = "WHO",
  title = "{WHO Statement on Caesarean Section Rates}",
  year = 2015,
  note= "[Online; accessed 7-Feb-2015]"
}

@article{ molina,
  author = "Molina, G and Weiser, TG and Lipsitz, SR and Esquivel, MM and Uribe-Leitz, T and Azad, T and Shah, N and Semrau, K and Berry, WR and Gawande, AA and Haynes, AB",
  year = 2015,
  title = "{Relationship Between Cesarean Delivery Rate and Maternal and Neonatal Mortality}",
  journal = "JAMA 314",
  volume = "21",
  pages = "2263–70"
}

Output in one page where you see the problem with Molina

Complication After adding \usepackage{natbib} in beginning

Mico's solution solves the initial bug but causes a complication. I get the strange top-bar references in each slide

enter image description here

Why is there the references top-bar?

How can you limit the amount of authors in the bibliography of Beamer?

  • Your write-up is a bit confusing. You mention an earlier posting that uses biblatex, yet your example code would not appear to make use of biblatex at all and, instead, use BibTeX. Please clarify. – Mico Feb 25 '16 at 21:10
  • @Mico The other thread is in biblatex. This one is in BibTeX. – Léo Léopold Hertz 준영 Feb 25 '16 at 21:13
  • Why even mention a biblatex-related thread that's of no relevance for the problem at hand? – Mico Feb 25 '16 at 21:33
  • @Mico Just to compare two similar cases with two different packages. – Léo Léopold Hertz 준영 Feb 25 '16 at 21:42
  • You ask, "Why is there ... "References" [in the] top-bar?" Because the beamer theme you've chosen places the titles of numbered and unnumbered section headers in the top-bar. The instruction \bibliography generates an unnumbered section header named, you guessed it, "References". Which beamer theme(s) do you use? – Mico Feb 25 '16 at 22:15

Since you're using the IEEEtranN bibliography style -- hint: the final N in IEEEtranN stands for "natbib" -- you should load the natbib citation management package. Once you do that, you'll get the desired, i.e., truncated list of authors in the citation call-outs generated by \cite.

  • I got a complication after adding \usepackage{natbib} in the beginning. I updated the body. – Léo Léopold Hertz 준영 Feb 25 '16 at 21:40
  • The "References" label is generated by the \bibliography instruction. If you don't want the label to show up, you'll need to change one or more beamer themes. I suggest that you start with \useouthertheme{default} and see if you like the result. If it's not to your liking, and if you can't find a suitable theme in chapter 16 of the beamer user guide, may I suggest that you post a new query? The theme issue is not exactly closely related to the issue of the proper usage of the IEEEtranN bibliography style. – Mico Feb 25 '16 at 22:05
  • Yes. I extended the thread here http://tex.stackexchange.com/q/296032/13173 – Léo Léopold Hertz 준영 Feb 26 '16 at 05:58

    @Masi - Thanks for posting a new query. I've left a comment there, asking you to state which beamer theme you use. As posted, the MWE produces no bar along the top of the page. – Mico Feb 26 '16 at 06:06
  • Can you force two authors go to et al mode too? Now et al starts only if there are three authors or more when you cite. – Léo Léopold Hertz 준영 Apr 12 '16 at 19:08

    @masi - It could be done, but it would require quite a bit of (re)programming of some of the functions in IEEEtranN.bst. It would also be rather unusual, typographically speaking. As it wouldn't actually save that much space -- compare "Brown and Smith (2009)" vs. "Brown et al. (2009)", I wouldn't recommend doing it. – Mico Apr 12 '16 at 19:18
