create bibliography in the order as the input in bibtex using elsarticle

Question

I am trying to put my article in the revised version using "elsarticle.cls", format "number" and bibtex as required by the journal.

My question is that the bibliography is created in the order of citation in my article, but I want to create a bibliography in the order as I input in bibtex ( where I sort the reference according to the alphabeta of the last name of authors in bibtex) not depending on the order of citation.

Any help is appreciated!

Here is the relevant code I used in the article.

---

\documentclass[preprint]{elsarticle}
\usepackage{lineno,hyperref}
\begin{document}
\section{1}
\bibliography{mybibfile}
\bibliographystyle{elsarticle-num}
\end{document}

Answer 1

You can follow the example here: Bibliography style with elsarticle. Specifically, you need to specify authoryear in the documentclass options. \bibliographystyle needs to be elsarticle-harv.

\begin{filecontents*}{\jobname.bib}
@article{Diamond1965,
 author={J. A. L. Diamond},
 title={Some Like It Hot},
 journal={J. High Level Cinema},
 year={1965},
}
\end{filecontents*}

\documentclass[authoryear]{elsarticle}

\usepackage[colorlinks=true,linkcolor=black, citecolor=blue, urlcolor=blue]{hyperref}

\begin{document}

\section{The Model}

The main environment modifies that of \cite{Diamond1965}, into two main dimensions

\bibliographystyle{elsarticle-harv}
\bibliography{\jobname}

\end{document}
