The full compiled Writer Guide v3.4 has been published to the documentation wiki (ODT, PDF).
Tomorrow I’ll publish the printed version, if Lulu.com cooperates. Will post again when that’s done.
A few of the chapter files on the wiki differ in minor ways from the chapters in the full book. When I get a chance, I will be revising and replacing the chapter files to match the book.
Huge thanks to everyone on the LibreOffice Documentation Team who helped get this book done.
