[1] Doe, Joe et al. Some journal. 2004.
[2] Doe, Jane et al. Some journal. 2003.
while many documents need something like:
1. Doe, Joe et al. Some journal. 2004.
2. Doe, Jane et al. Some journal. 2003.
This sort of change may be achieved by many of the “general” citation packages; for example, in natbib, it’s as simple as:
\renewcommand{\bibnumfmt}[1]{#1.}
but if you’re not using such a package, the following internal LaTeX commands, in the preamble of your document, will do the job:
\makeatletter \renewcommand*{\@biblabel}[1]{\hfill#1.} \makeatother
