I am a heavy user of bibtex, but I am puzzled over the 'date'
field. Publications have a 'year' ok, sometimes a 'month', but never
have I seen a 'day'. So how would a user enter (YYYY-MM-DD)? Is it
perhaps the date of entry of the record in to the file? Sorry to butt
in, but I am curious.

Best wishes,

Colin Baxter.
