Abstract:

This article does not address the (important) questions of when a single-sourcing methodology is a good solution to an information delivery problem ('good' here meaning saving time and money while maintaining or improving the quality of the resulting deliverables). Instead, I'm looking only at the editor's involvement in the project.
