There are "magazine size" storage boxes (same composition as the standard comic book short box or long box) that fit both modules and soft/hardcover rulebooks.  You can also buy these in plastic, but those become fairly pricey once you start adding it all up.

The amazon page has a lot of comments about the BCW boxes being too thin, any issues with them?

What do you guys do for box sets? I have a few in shrink and am always worried about tearing the shrink because I dont have a good way of storing them other than just flat on a shelf.

I use various boxes from bagsunlimited.com including these sturdy bad boys:

I have about 30 of them and I love them.

I believe it's just preference (unless you're talking about box sets, then yes, the depth of the stack matters).  You can access the material much easier if you don't stack them.

Stacking modules or magazines is akin to stacking comic books; it causes spine roll over time, and spine roll is bad.  You want to bag and board them and stand them up.  And you don't want to cram the materials into boxes either.  Here's an article on preserving comics, but the advice applies to lots of D&D items as well.

I try to minimize spine roll by alternating each book by 180 degrees.  It makes the stack more even (but not perfect due to variances in each book such as page count, cover material, and binding type).

Do you guys use drawer-style storage boxes?

For my modules and for a box to work out of while I catalog things that I am purchasing whatever they may be. I am using Banker's Boxes that I got at one of the big Box office supply stores. They are designed to hold a lot of paper so are fairly sturdy built and fold together easy. The ones I am using came 10 boxes to a box. I think the box of 10 was like $20 to $25. They are not going to fall apart with a lot of weight in them. But cardboard won't protect from water of course. (Live in a flood plane?)  The one issue I have with that for now is the books will have to be set in on one of their long edges. I haven't thought thought whether spine edge or pages edge down would be better.

As for boxed sets, I have to agree about using Sterilite. Hard outer shells FTW!

Update: I did bag and board modules before stacking them, but I dont stack them now. Ikea.

I just keep mine bagged & boarded on my shelf.

BCW Magazine Boxes would probably be best.
