digital copies are so much easier to deal with and transport (the movers and my spouse will thank you!), plus easier to search through.
Well, one can lose a lot via digital means, too (back-up, back-up...).
And, for me, I'm happy enuff reaching up to either of two stacks of
KMs (and the few oldest ones vertically standing on shelf) and pulling
out the whichever (now that I've annotated covering envelopes w/#!).
Yeah, Search can be better, sure. (To that end, though, I at least
thought to further annotate envelopes and also have a crude listing
of topics of interest to me.) s/low-tech, but colorful!
Oh, and annotations go into KMs from time to time, too.
