Disc or Paper

I was wondering how many of you have got manuals on disc and how many have the hard copies (old school) manuals.

I want to update/expand my resources.
I only have one manual on disc at the moment (1970/71) Mopar Master Parts Book).
And a few various paper reference manuals (quite a few, but never too much).
I kinda like the disc idea (as far as won't rip or stain, easy storage...), but searching through it is somewhat of a pain (XN viewer), but 1/2 the price of printed copies.

Any of you purchased manuals on disc ? Like em ?
I haven't had a copy of both disc and print to compare.

Is it time for a PC in the cave?

What do you all think ?
