How to cite the BNF?

[Russ93]

Hi,
For my Advanced Higher Biology Investigation Report I have to give a list of references. One of my references I have used is the BNF. I am struggling to do this though!

We have to do our references like:

Author(s), (surname followed by initials) (year of publication) Title, Publisher, Place of Publication, Page number(s)

But I haven't a clue about author(s) for the BNF - what should I put down?

Thanks,
Russ

I referenced it in my final year project as follows:

British Medical Association and the Royal Pharmaceutical Society of Great Britain. British National Formulary. 58th ed. UK: BMJ Publishing Group. 2009.

Thanks, that's perfect!
