An History of Outlining (and STOP)
The STOP teams brilliant practical approach to outlining also looks forward to a number of activities that have become more convenient thanks to electronic outlining software--collaborative work on organization, visual display of a verbal structure, an iterative process of research, outlining, and drafting focused on the same document, and the large organizations need for standard templates defining the structure of generic modules. In these ways, the STOP team are forerunners for practices that even today are avant garde.
