No it is not a spiraled book. It would be way to large. There are 3 books eahc being a volume. Each book is about 2.5"-3" thick and FULL of information. I haven't seen the download you are talking about yet.
I'm very happy with my purchase even though it is expensive but the detail at which the book goes into regarding removal of parts, exploded views, electronics information, etc will be very very handy for myself or a technician.
