Cheree, I couldn't find either of those books using those exact titles. There were three other books listed under the Pygmalion Project (vols 1-3 are the Artisan, the Guardian, and the Idealist), but you probably already knew that. If you haven't already tried this, contact the publisher and see if they have back stock of those title or if they have any plans on re-releasing them. Keirsey has his own website with books available here:
