Chapters of the OOo Writer Guide, revised for v3.3, are here:
http://www.oooauthors.org/english/userguide3/writer3/V3_3_revisions/
We'll be officially publishing them as soon as someone gets around to
it, but I think they are ready for others to transform into LibO docs.
Several have changed significantly from the earlier draft version placed
on the LibO wiki some time ago.
