I must congratulate everyone who is responsible for organising this course, its materials and its forums - the quality of everything is absolutely superb - I never imagined that a free course could be of such high quality.
I noticed that projects 7 onwards do not seem to contain online PDFs of their related book chapters. Is this deliberate?
I am guessing that it is indeed deliberate in that you are encouraging participants to purchase the actual printed book. If that is the case then I would be more than happy to purchase it - is there a PDF version that can be purchased from somewhere?
