This would do nicely.

I just saw this fab French industrial book case that I could SO easily repro on my own.
I was reviewing the extensive and wonderful "book storage roundup" which is offered by Design*Sponge, but I was referred by Jamie over at i suwanee.

This could be a cool alternative to Paul's condo book storage, and it could go behind the chair I want to put there (for additional company seating). And since it has massive casters, it would build consistency with the desk I'm going to build (that drafting table I have, but I'm going to replace the saw horses with HON 2-drawer filing cabinets with commercial casters on the bottom for height and mobility, and of course a bit of manliness.
