Hi Ron,
You are partly correct!
You can get the 'book'. It's not a paperback book but an electronic book.
It's not a pdf, which can be copied easier (since the book is copyright), but
a more secure version of an electronic book. It can be downloaded to your
computer and is interactive - it's like browsing the internet when you open
it.
Once you purchase it - you are directed to a download page and an email
is automatically generated with a unique username and password. No one
person has the same info. The username and password is used to register
the book.
You do have the option of printing as well - however, it's got over 700+ pages
as well as over 300 images . . . printing it would be - well - you know - alot!
Hope this helps!
Happy Reefing
