OxygenOffice Professional is a free and open source enhancement of official OpenOffice.org. The OxygenOffice Professional Team has modified the source of OpenOffice.org and bundled lot of extras with it. Here are just a few of the extras you get with OxygenOffice Professional: More than 3,400 graphics are included, both clip art and photos. These pictures are integrated into the gallery and can easily be placed into any OxygenOffice document. Several templates and sample documents are included, as well as over 90 fonts. The extras are integrated by default in the installation of OxygenOffice Professional, but they are optional, so the user can decide what parts to include and what parts to leave out. These extra templates, fonts, and graphics are free for both personal and professional use. Additional tools like OOoWikipedia, which can search the free on-line encyclopedia Wikipedia, are also included.
