Correct me if I'm wrong.. I think the Books <http://zopewiki.org/Books>, especially the Zope Book and Zope Developers' Guide, are the core of Zope documentation. I am wondering how it would be if we used them as a sort of skeleton for the content on this wiki, and perhaps positioned these pages more as complementary notes/addenda to the books.
For example. Under the ZopeBook <http://zopewiki.org/ZopeBook> and ZopeDevelopersGuide <http://zopewiki.org/ZopeDevelopersGuide> pages, we could make sure we have a page corresponding to each chapter in the current book. Each page would link to the original in a consistent way. The chapter content could be mirrored here or not. We could organize additional notes, docs, GeneralTopics <http://zopewiki.org/GeneralTopics> etc. corresponding to the chapter's topic on or under the page, to whatever degree seems to make sense.
Or, we can continue letting this wiki develop its own fresh structure. But I think there's no harm in trying it out.
