I am not sure that an electronic copy would be very useful without having access to a hardcopy.
Besides not everyone has a laptop on their side as they go about their daily routines.
I have types several of the chapters into word and scanned the pictures for my own study. Figure eventually I will get all of them done and then Version 7 will be published...hmmm maybe if that is the case I should get typing...

..
Wonder if and when management will ever give a date for the publication...
