For the uninitiated Buy John Foreman's books. I have several. They are ground-breaking for their time and still constitute a sound basis for a lot of research. They are excellent. Mistakes are present, but not anywhere near an argument against their value. Easily cross-referenced in other works or on this forum (is that not part of our enjoyment of the discussion!). As Nick writes, and we know from college, university (and business) we can read and re-read our work and always auto-correct in our own mind... only to find a lecturer's red-pencil underlining an obvious mistake.
