You can buy the paperback book at amazon or as one of the many electronic versions.
I can't say the "cheat sheets" aren't useful, but the big problem with learning position this way is that it is teaching you by rote examples. The book isolates various types of positional shots on both a half table and full table and shows you the speed and spin to make the cue ball take a particular route. You can certainly learn that way but it takes longer without developing a foundational understanding for why you're combining that speed and spin. As such, a good accompaniment to that would be something like Mike Page's (FargoBilliards) excellent two part video series on cue ball control on youtube.
Uh, Dr. Dave? His Visual Encyclopedia companion sets (Pool Shots & Pool Practice, with Tom Ross and Bob Jewett, respectively), at 10 DVDs total, are still the most comprehensive and authoritative collection of basic-to-advanced practical techniques and practices. Every pool library should include the Visual Encyclopedias.

Maybe not best instructional material but more an aid. Pocket reducers. For $35.00 you have something that forces you to concentrate more, slow down, and aim better. Dollar for dollar I personally dont know anything that can improve your game any better.
hmm, I respectfully disagree, I think tight pockets are overrated as training tools...
Anyone ever tried any of these? The website does look interesting.
Are there any actual books or is it all "e-book" stuff that you need to print out? Just curious.
Several different resources on there.
As far as underrated instructional books go I have one that I never seen anyone mention that was written by a guy I've never heard anything about, but it seems to be chock full of good information and various shots, safeties, and drills that have helped me out a lot, and that I keep going back to. It's literally called "The Best Damn Pool Instruction Book, Period" by a guy named Ronald L. Schneider. The title is pretty terrible and cheesy and I bought it on a whim at Barnes and Noble one time, but I still think it has a lot of valuable information in it.
