OpenOffice.org books focusing on specific components

Continuing my research of books on OpenOffice. org, the open source alternative to Microsoft Office, I found a few books that focus on single programs of the suite:

OpenOffice Writer

• OpenOffice.org 2.0 Writer Guide by the OOoAuthors.org, a volunteer group of documentation writers.
• OpenOffice.org Writer : The Free Alternative to Microsoft Word by Jean Weber covers version 1.0 or 1.1. Jean Weber did write this book originally in self publishing and O'Reilley later decided to publish the book which gave it a wider audience.
• Writer for Writers by Dmitri Popov
