The `thebibliography' environment produces a bibliography or
reference list. In the `article' class, this reference list is
labelled "References"; in the `report' class, it is labelled
"Bibliography".
* `widest-label': Text that, when printed, is approximately as wide
as the widest item label produces by the `\bibitem' commands.
