Moira, I guess I qualify as a UK correspondent,  so here is the URL to the 
'John Innes Centre'.  

http://www.jic.bbsrc.ac.uk/

I also had a look for the book at various sites, but it does not seem to 
be available.  Shame.

I have had occasion to use this super poo, and also had a few 'dark looks' 
from my neighbours, let alone the distressed gaspings of my wife when she 
came out to hang the washing ....    But it's certainly worth it, as the
payoff
in plant growth is so obvious.

One way to diminish the pong can be achieved by watering it immediately 
after spreading.
