[Tex/LaTex] How to change the delimiter for \citeauthor with multiple references and add “and” between the last two

bibtexcitingnatbib

\citeauthor{iso9241-5,ansi2007,osha3092}

produces

International Organization for Standardization;
Human Factors and Ergonomics Society;
Occupational Safety and Health Administration

Is there a pretty command to make it produce

International Organization for Standardization,
Human Factors and Ergonomics Society and
Occupational Safety and Health Administration

so I don't have to write

\citeauthor{iso9241-5}, \citeauthor{ansi2007} and \citeauthor{osha3092}

Best Answer

To format the punctuation of natbib the package provides the command \setcitestyle The character between citations can be set in the following way:

\setcitestyle{comma}

which is equal to

\setcitestyle{citesep={,}}

Here an example that can do what you want: (A bug is possible)

\documentclass{book}

[Tex/LaTex] Is is possible to not abbreviate the author name of only one reference in the bibliography

Your problem is not caused by IEEEabrv.bib, which simply contains the abbreviated names of IEEE journals; it is rather caused by the style IEEEtran.bst, which is programmed to abbreviate author names.

According to this, maybe you could write your author as

author = {{\relax World Health Organization} and others}

[Tex/LaTex] How to cite two different authors with the same surname in BibTeX

The apacite package (which can be used with natbib) does this automatically. Note however, if both authors also have the same initial, (as originally stated in your question title but not your actual example) it will fail.

The proper APA citation form for these is "FirstName LastName (Year)" and in the bibliography "LastName, F. [FirstName] (Year)". The apacite package explicitly says it can't deal with such cases.

\begin{filecontents}{\jobname.bib}
@Book{CGeertz:Negara,
  author =  {Geertz, Clifford},
  title =   {Negara: The Theatre State in 19th Century {Bali}},
  publisher =   {Princeton},
  year =    {1981},
}

@Book{HGeertz:BalineseTemple,
  author =  {Geertz, Hildred},
  title =   {The Life of a {Balinese} Temple},
  publisher =   {University of Hawaii Press},
  year =    {2004},
}
\end{filecontents}
\documentclass{article}
\usepackage[natbibapa]{apacite}
\bibliographystyle{apacite}

\begin{document}
\cite{CGeertz:Negara, HGeertz:BalineseTemple}
\bibliography{\jobname}
\end{document}

`biblatex-apa` deals with this correctly

Although you said you didn't want to use biblatex, the biblatex-apa package does deal with these cases properly:

\begin{filecontents}{\jobname.bib}
@Book{Smith1994,
  author =  {Smith, John},
  title =   {A book by John Smith},
  publisher =   {Princeton},
  year =    {1994},
}

@Book{Smith1999,
  author =  {Smith, James},
  title =   {A book by James Smith},
  publisher =   {University of Hawaii Press},
  year =    {1999},
}
\end{filecontents}
\documentclass[11pt]{article}
\usepackage[american]{babel} 
\usepackage{csquotes} 
\usepackage[style=apa,backend=biber]{biblatex}
\DeclareLanguageMapping{american}{american-apa}

\begin{document}
