EDIT 2014: I am no longer maintaining this blog and website, because I am no longer using this program for my daily work. I am using LibreOffice, another descendent of the old OpenOffice.org. It is developed by an active and enthusiastic community. I have a blog about it here: Taming LibreOffice.
Apache OpenOffice (AOO) is the new name for OpenOffice.org (OOo) from version 3.4. It is a suite of programs for word processing, spreadsheets, presentations, databases, and drawings. It is free to download, use, and distribute. It is available in many languages and runs on Linux, Mac, Windows, and other operating systems. Its native file formats are OpenDocument (*.ODT, *.ODS, *.ODP, etc.), but it can open and save to many other formats, including Microsoft Office formats (*.DOC, *.XLS, *.PPT, etc.).
To get the program, go to the OpenOffice.org website. Good introductions are Introducing OpenOffice.org (PDF).

Some of the blog posts on this site are about LibreOffice, a similar program. I have now created a separate website for material about LibreOffice; see Taming LibreOffice.
Note: Some of the material on this site may be out of date. Some of it was originally written for OpenOffice.org 1.1.3 and has not been updated for OOo 2 or OOo 3. Some details have changed, but the general information is still relevant. I am updating the pages as I find time.
Books on OpenOffice.org
In addition to the books listed in the sidebar, others may be given on this page; I haven’t updated the book list for some time, other than adding those published by ODFAuthors.
