Hi Howard, Is this for paper or on-line publication? If paper, make it two completely separate dox - let the reader choose which to use/buy. But for production, still use a single source. If online, use the peeling of the onion approach - present the steps in outline form hyperlinked to further layers of single-sourced detail - let the reader do the drilling.
