As you are obviously impressed by the HOL site, why not help support it, make a donation or give some of your time. As Cody has said HOL has taken an exceptional amount of time to collect the mass of information it contains. This info was compiled to be used by everyone who loves the Amiga, not for people to just steal and keep it in there own private collection.
Maybe we have read you wrong and your reasons are truly selfless, perhaps you where worried such a great site would be destroyed by a freakyweaky accident and it would be lost forever. Then you, having a copy of the whole site on DVD would be able to hand over your disk and save HOL from disaster. I don’t know for sure but I think the HOL team have made previsions for such an occurrence so I don’t think they will need another back up of it. Thanks for trying to help though.
