# How to make citations appear within parentheses () instead of square brackets [ ]? [duplicate]

I am using the vancouver.bst which conforms to the ICMJE (international committee of medical journal editors) How do I make the citations in the text appear in parentheses, e.g., (3), rather than in brackets [3]?

The style vancouver is compatible with the package natbib. So you can load the package natbib with the option round to achieve your requirements.

\documentclass[]{article}
\usepackage[numbers,round]{natbib}
\begin{document}
\cite{book-full}
\bibliographystyle{vancouver}
\bibliography{xampl}
\end{document}


• Thanks, that worked! I now need to get consecutive citations in the text to go from (1,2,3) to (1--3)....any ideas? – user2414716 Jul 19 '13 at 20:23
• ...I just found it. I used \usepackage[numbers,round,sort&compress]{natbib} Thanks again. – user2414716 Jul 19 '13 at 20:37
• @user2414716: Your second question doesn't belong to your original question. The format of our site prefer asking a new/separate question. – Marco Daniel Jul 19 '13 at 20:38
