order of appearance of authors in bibliographic entries

Question

Im trying to have the bibliographic list defined for my document using natbib. While styles such as unsrtnat gives me a the references in order of appearance in text, however, I have a problem that cannot get around. Basically if a reference is supposed to look like:

Tyson J.P. Dikstra M. Holmes F.M.R. Theoretical Analysis on Effect of Anomalous Low Friction. International journal of Placticity, 34(3-4):413, 1997.

after typesetting it appears as :

Dikstra M. Holmes F.M.R. Tyson J.P. Theoretical Analysis on Effect of Anomalous Low Friction. International journal of Placticity, 34(3-4):413, 1997.

In other words, it puts the first author in the last place. Is there any method of getting around this?

\usepackage[round,comma]{natbib}

\begin{document}


As an alternative method of analysis,\citep{Tyson1997} ...


\bibliographystyle{unsrtnat} 
\bibliography{refs}


\end{document}

The entry as it appears in the .bib file is :

@ARTICLE{Tyson1997,
author={Tyson, J.P., Dikstra, M., Holmes, F.M.R.},
title={Theoretical Analysis on Effect of Anomalous Low Friction.},
journal={International journal of Plasticity},
year={1997},
volume={34},
number={3-4},
pages={413},
document_type={Article}
}

Sorry egreg, This is my 1st post. I was not aware of the rules.

Answer 1

You are probably using a bad syntax for the author names:

author={Tyson, J. P. and Dikstra, M. and Holmes, F. M. R.},

is the correct input so that BibTeX can parse the list of authors. I get the same output as you obtain with

author={Tyson J.P., Dikstra M. and Holmes F.M.R.},

that BibTeX parses, according to its rules, as two authors: the first has a family name "Tyson J.P.", first name "Dikstra" and middle name "M.". The second author has first name "Holmes" and family name "F.M.R.".

With your input

author={Tyson, J.P., Dikstra, M., Holmes, F.M.R.},

things are worse, because BibTeX finds too many commas and issues nine error messages.

Authors should be listed separated by the keyword and; you have the choice of listing each author as

<first name> <middle name(s)> <family name>

or in the clearer way

<family name>, <first name> <middle name(s)>
