BibTeX, biblatex and biber ⇒ Citations without square brackets

[marcdein]

A journal requires citations to be in the form

(John (1999); Peter (2000); and Paul (2003)) or (John (1993) and Peter (2000))

This looks like BibTeX style authordate1, for example, apart from the lack of square brackets. Is there any way to get rid of them?

Thanks.

You should check out some of the options to the natbib package; one of them is the type of brackets to use. I have found this site to be useful: http://merkel.zoneo.net/Latex/natbib.php
