Significant progress has been made since the second working group meeting as the group has now begun generating content for the book. The discussion centered around a central presentation to which each member has contributed and which summarized each sub-chapter of the book. Both redundant and missing content were discussed which has resulted in a revised chapter plan. A full version of the meeting minutes are available to view here. The next steps for the group are to produce final draft versions of their sub-chapters by April 2009, at which time the content will go through an internal review process.
