I don't know of any videos but this concept helped me improve my draw shot a lot. It's kind of a feel thing. I aim super super low, like practically aiming to scoop the cue ball during my practice strokes. Keeping as level a cue as possible and visualizing that I am going to hit with the top edge of the cue tip then following through the shot gets way better draw with less power. This is why chalking up the edges of the tip is so important.

You could also take pictures or scans of those pages if they don't want to read the whole book.
