You did an awesome job and produced a great primer that will answer tons of questions for the beginners getting into photography. Great job making it easy to understand the tough concepts surrounding the variables that control exposure and how they relate to depth of field. Most of the explanations I remember reading when I needed them went too deep and put me to sleep rather than making the concepts understandable. Looking forward to going back to p 87 to check out the links you listed.
Great job Joe!
