Use {{reflist}} instead of <references/> to create multi-column footnote lists for heavily cited articles.
You can see the 2-column footnote layout at the bottom of this article!

This template and the exerpted documentaiton below are lifted from based on the Wikimedia template {{reflist}}. Both have 1:1 correlation with the originating Wikimedia template as of the July 9 2007 revision. Don't expect that to last, even at maturity the originating template is receiving ~1 minor tweak per month. However it is unlikely to see fundamental revision (and require re-porting) until CSS3 reaches a tipping point.

Usage

Use this template to create a reference list in an article with a small font. Note that there is no consensus that small font size should always for all references; when normal-sized font is more appropriate on an article, use <references /> instead.

If used with no parameters, it will produce a reference list with a single column.

Multiple columns

Using {{reflist|2}} will create a two-column reference list, and {{reflist|3}} will create a three-column list.

Using {{reflist|colwidth=30em}} will allow the browser to automatically choose the number of columns based on the width of the web browser. Choose a column width that's appropriate for the average width of the references on the page.

Note: multiple columns currently render properly only in Mozilla Firefox and other Gecko-based browsers,[1] though the feature is included in CSS3, so it should work for a larger number of browsers in the future.[2]
