Thanks, Ihor. That found it.

The bibtex entry had:
author = {BIS},

Change to:
author = {{Bank for International Settlements}},

and it all works a treat.

A short random test shows that the export chokes when there is a single
name for an author. Again an example:
author = {{Wolfsberg Group}} works fine;
author = {{Wolfsberg}} chokes.

Thanks to you and to Bruce for the help.

Cheers,
Alan
