# Only last name for natbib citep [duplicate]

I want my citations to be shown as (LastName, year) instead of (LastName Initials, year). I am using the natbib package, with setting 'authoryear'.

Below a minimilistic example:

My .tex file:

\documentclass[]{article}
\usepackage[authoryear]{natbib}

\begin{document}

Document body text with citations \\
\citep{Bertram91} \\
\citep{Bertram06} \\

\bibliographystyle{authordate1}
\bibliography{myreferences}

\end{document}


And my .bib file:

@article{Bertram91,
author = "Bertram C.D., Raymond C.J.",
title = "Measurements of wave speed...",
journal = "Med. and Biol. Eng. and Comput.",
volume = "29",
year = "1991",
pages = "493--500",
}

@article{Bertram06,
author = "Bertram C.D., Tscherry J.",
title = "The onset of flow-rate...",
journal = "Journal of Fluids and Structures",
volume = "22",
year = "2006",
pages = "1029--1045",
}


This gives the output:

I do NOT want the initials in the citation.

• No need to thank or sign in your question. The nice MWE should make it easy for you to get help. – Ethan Bolker Dec 23 '13 at 13:47
• Your input file seems not exactly to conform to the BibTeX syntax. The name format is Last, First and Last, First, so you need author = "Bertram, C. D. and Raymond, C. J." and author = "Bertram, C. D. and Tscherry, J." (or author = " C. D. Bertram and C. J. Raymond" and author = "C. D. Bertram and J. Tscherry"). – moewe Dec 23 '13 at 14:03
• Wow that did change the citations in a major way :) It is now showing correctly. Thank you very much! – Xomesss Dec 23 '13 at 14:47
• @moewe No, it's a completely different problem. – egreg Sep 6 '15 at 6:49
• @egreg Blast! Of course, I must have been still a bit drowsy. Sorry about that. I assume How should I type author names in a bib file? is much more appropriate, then. I git too entangled in the initials block, though that needed change as well. – moewe Sep 6 '15 at 6:52

According to your input (and to BibTeX rules), the paper Bertram91 has just one author, whose family name is “Bertram C.D.” and given name is “ Raymond C.J.”.

An author should be given in the form

Family, Given


(also Given Family can be used, but it's better to stick with a scheme; Given can of course be just the initials).

Authors must be separated by and. So the correct syntax for your paper is

@article{Bertram91,
author = "Bertram, C.D. and Raymond, C.J.",
[...]

• Would you mind if I changed the initials block as in the question I initially voted this to be a duplicate of? – moewe Sep 6 '15 at 6:58
