James O'Heare Aggression workbook and Brenda Aloff does one too, name escapes me, look on american site called Dogwise for more ideas.
I read up as I had a dog with aggression issues and the James O'Heare book was a great manual for me but my inspiration came from a book Bringing light to shadow, which is more of a diary of someone dealing with an aggressive dog.
Personally Jean Donaldson's fight was not for me and neither was the Barbara Sykes. But the Turid Rugass was interesting and I do use bits from that even now.
Also not sure about recommending another site but, Taking the lead forum, is really useful and lots of people post about books there
