Hi: Further to the discussion on Wiki.
There are two very interesting collaboration models . Wiki model where contributing authors write different pages/content and then URLs collated on a single page ties them up. eg. most wikis (MediaWiki) . Collaborative Book model where the overall knowledge created is structured as a book. Different authors contribute information/knowledge/content in different sections/chapters of the book. In addition to collating the URLs (which are logically connected here), one also can order the chapters/sections for better flow of logic or chronology of events. When the user clicks the [Printable version], (s)he can see the entire book in a single page. This can be easily printed. eg. Drupal In fact, twincling.org is powerd by Drupal 5 thanks Saifi.
