Many books are designed as a core text supplemented by additional content in the form of footnotes, endnotes, references, appendices, supporting data, reviews, and so on. We have extended this idea in a book titled /The Discipline of Organizing/ by tagging supplemental content by discipline, effectively creating a family of related texts suitable for different courses and perspectives. This content architecture lends itself to implementation in ebook and browser formats. We are assembling some combinations of content and deploying them as editions targeted for a particular context, and we are also developing dynamic ebooks in which readers can decide to include, transclude, or exclude content as they read. http://disciplineoforganizing.org/
