# A little bug in alphadin.bst

I found a little bug in alphadin.bst. If you use the multibib package in LaTeX in combination with the alphadin.bst bibliography style, it can happen that the “\etalchar” command will be defined twice. This will eventually stop the LaTeX interpreter with an error like this:

LaTeX Error: Command \etalchar already defined.

A simple solution is to edit the alphadin.bst file, locate (under FUNCTION {begin.bib} ) and replace

“\newcommand{\etalchar}[1]{\$^{#1}\$}”

with

“\providecommand{\etalchar}[1]{\$^{#1}\$}”

Sure, I wanted to report that bug but it is not obvious where to report?
