Creating a Book with OpenOffice
Newsforge’s Dmitir Popov writes Creating a Book with OpenOffice.org Writer.
In the comments, a reader discusses a book that he has written (and keeps updated) with OpenOffice: A Guide to Rock Climbs at Bon Echo, 3rd Edition.
And, of course, my own book was written in OpenOffice.org. (Appropriately, since it is The Tiny Guide to OpenOffice.org.)
