Very cool. I own the originals and the 4th but sadly I have to admit that even though I am a reasonably accomplished developer with a couple of CS degrees I have a hard time understanding this work and have not yet really read it. I feel like I am publicly admitting failure just posting this. I still have time to make sure these are not just bookshelf decorations though.
I suggest skipping around on an "as needed" basis.
Try Volume 1, Section 2.2 "Linear Lists", as a starting point. I promise you its an easier read than you expect. Despite being relatively easy material, you will probably learn something about arrays with just maybe ~3 or ~4 pages worth of reading material.
Start at the start of Section 2.2. Maybe work your way backwards to Section 2.1 as you realize its not as hard as you think (so you start at the "proper" starting point). And then go on from there.
Its really basic stuff. But hitting "rock bottom" on the subject of arrays, stacks, queues, and such is fascinating.
