As Volume II is shaping up and both I and III maturing, it's time to think about the promised hardcover format. Following a question by GeoSn0w, some clarifications and a question to you:
Each book's page count is around or over 500 pages. This means the combined book will be 1500 pages. That alone weights 3.5 kgs (last I checked), and I haven't factored the hardcover. And that's assuming the lightest paper I could find - the hardcover will also be colorful, so I'm guessing the paper could be 25% or more heavier - bring us to 4.5kg of paper, and with the cover itself (remember, hard = heavy) almost 5 kilograms! That's over 10 pounds, people!
So - There's no way I can put everything into one volume, UNLESS I do a three ring binder format. I kind of like the idea - the UNIX manuals of old, when in paper, were also binders. And this does have the option of adding pages to it. So the question for you is (and thank you for letting me know!)
