Remove "and" between authors in bibliography

Question

I'd like to remove the "and" between the authors in my bibliography. Currently, I have authors listed as such author1, author2, and author3 and author1 and author2.

Desired output: author1, author2, author3 and author1, author

This is my first time using Latex, so while I believe this link is helpful, I've been unable to implement it. Since this is also my first post about Latex, I am also open to feedback on how to post a more informative question!

Code below:

\documentclass[12pt]{article}
% --------------- 10 POINT FONT FOR CAPTIONS ------------------
\usepackage[font=footnotesize, skip=0pt]{caption}
% --------------- NY TIMES FONT -------------------------------
\usepackage{times}
% --------------- CITATIONS -------------------------------
\usepackage[super,sort&compress]{natbib}

\usepackage{paralist}
\let\olditem\item
\renewenvironment{thebibliography}[1]{%
  \section*{\refname}
  \let\par\relax\let\newblock\relax
  \renewcommand{\item}[1][]{\olditem}%
  \inparaenum}{\endinparaenum}

\begin{document}

\fontsize{11pt}{11pt}\selectfont
\bibliographystyle{unsrtnat}
\bibliography{refs}

\end{document}

And example citation:

@article{boyd2011cultural,
  author="Boyd and Richerson and Henrich",
  journal={Proc. Natl. Acad. Sci.},
  year={2011},
  publisher={National Acad Sciences}
}

Answer 1

Since you're using the unsrtnat bibliography style, I suggest you proceed as follows.

• Find the file unsrtnat.bst in your TeX distribution, make a copy of it, and call the copy, say, unsrtnat-noand.bst. (Don't edit an original, un-renamed file from the TeX distribution directly.)

• Open the file unsrtnat-noand.bst in a text editor. The program you use to edit your tex files will do fine.

• In the unsrtnat-noand.bst, find the function format.names. In my copy of the file, this function starts on line 216.

• In this function, find the following line (l. 228, probably):

                  'skip$
  

  Change it to

                   { "," * }
  

• Still within this function, find the following line (l. 232, probably):

                   { " and " * t * }
  

  Change it to

                   { " " * t * } 
  

  I.e., delete and , but leave one blank space in the first string.

• Save the file unsrtnat-noand.bst, either in the folder where your main tex file is located or in a folder that's searched by BibTeX. If you choose the second option, be sure to update the filename database of your TeX distribution suitably.

• In your main tex file, change the instruction \bibliographystyle{unsrtnat} to \bibliographystyle{unsrtnat-noand} and perform a complete recompile cycle -- latex, bibtex, and latex twice more -- to fully propagate the change in the bib style file.

Here's an MWE (minimum working example) that demonstrates the outcome of this exercise.

\documentclass{article}
\begin{filecontents}[overwrite]{mybib.bib}
   @misc{ab,author="A and B",title="Thoughts",year=3002}
   @misc{abc,author="A and B and C",title="Thoughts",year=3003}
   @article{boyd2011cultural,
      author="Boyd and Richerson and Henrich",
      journal={Proc.\ Natl.\ Acad.\ Sci.},
      year={2011},
      publisher={National Acad Sciences}
   }
\end{filecontents}

\usepackage[super,sort&compress]{natbib}
\bibliographystyle{unsrtnat-noand}

\begin{document}
aaa\cite{ab}, bbb\cite{abc}, ccc\cite{boyd2011cultural}
\bibliography{mybib}
\end{document}

Answer 2

and is mean to tell bibliography engine that those are different authors. You set out come of the look with \setcitestyle{authoryear,open={((},close={))}} for example.

\usepackage[super,sort&compress]{natbib}
\bibliographystyle{unsrtnat}
\setcitestyle{none,open={((},close={))}}

to edit word and from bibliography try use \renewcommand{\harvardand}{,} or \renewcommand{\betweenauthors}{,}.
