Cite 5 authors in the first citation in your TeX file?

Question

The APA style manual website says:

[A]rticles with one or two authors include all names in every in-text citation; articles with three, four, or five authors include all names in the first in-text citation but are abbreviated to the first author name plus et al. upon subsequent citations; and articles with six or more authors are abbreviated to the first author name plus et al. for all in-text citations.

Is there a way to

• manually cite all authors in a citation of a paper with 5 authors, using \cite{...}

• have the above-described rule automatically performed by latex, so that I don't have to do it manually?

Answer 1

The apa style of biblatex will do this automatically (note: you need to use biber instead of bibtex)

\documentclass{article}
\usepackage[style=apa]{biblatex}
\addbibresource{biblatex-examples.bib}

\begin{document}
\cite{companion}

\cite{companion}

\printbibliography
\end{document}
