\noindent {\Large Examples of the bibliographic entries with many authors.}
\begin{itemize}
 \item This file uses ``\texttt{econ.bst}'' and ``\verb|bib_with_many_authors.bib|''.
\end{itemize}

\vspace*{1em}

In econ.bst, if the number of authors is greater than N1, only the first N2
authors' names are displayed in the reference part (and other authors' names are
omitted by "et el.").
\begin{itemize}
 \item N1 is determined by ``\texttt{bst.max.author.num}'' (the default value = 8).
 \item N2 is determined by ``\texttt{bst.max.author.num.displayed}'' (the default value = 3).
\end{itemize}

\noindent Examples of bibliographic entries with many authors.
\begin{itemize}
 \item \citet{Pilia_2020}, \citet{Abbott_2016}, \citet{LHC_Physics_Letters_20121}.
 \item \citet{Abbott_2016} and \citet{LHC_Physics_Letters_20121} have more than
       1000 authors (see the database in \verb|bib_with_many_authors.bib|).
\end{itemize}

\noindent \textbf{[Note]}

The bibtex program in ``TeX Live 2019'' generates the following error message when the
number of authors is very large. bibtex in ``TeX Live 2020'' works well.
