Thank you for all the suggestions for disk storage.  Sorry I asked an
oft-repeated-always-debated newbie question.  Should have searched the
archives first.  I participate on several hobby forums and know these
chestnuts give rise to groaning!

Based on all the ideas, my own thoughts, and available space, I think
I'll store vertically and loosely, in a box open to the front (air
exchange and space convenience), all projections facing the same way
(no projection snagging), with a hard-surfaced archival board sheet
between them (no plastic fumes, moisture build-up, slight cushioning).
It must be nice to have so many disks that weight is a problem!
