The online book follows on from the basic one you get with the softwear and goes into more complex operations. I did enquire if you could purchase the book and it was going to cost £35 but take 6 months? to get here. I have gradually been printing of the chapters as i need them and think i have about printed the whole thing now, 350 pages for PED10.
Amended, the book i got with my softwear is very basic, only goes into loading the softwear and basic operations.
