[texhax] Bibtex, ordering of bibliography items.

[Rolf Turner]

I have two papers by the same author, both dated 1971.

The later paper (which cites the first) gets listed *before*
the earlier paper in the bibliography, since its title comes
before the title of the earlier paper in an alphabetical ordering.

I would like to get the earlier paper listed first.  Is there
any simple way to achieve this?  I am using vanilla bibtex and
\bibliographystyle{plain}.

Thanks for any tips.

	cheers,
