Using Zotero to manage OpenOffice.org bibliographies
If OpenOffice.org's own bibliography feature doesn't really cut it for you, you have several choices. One popular bibliography solution is Bibus, a cross-platform tool that integrates nicely with OpenOffice.org. It is, however, not the only bibliographical tool out there. In fact, there is another nifty tool called Zotero that turns Firefox into a powerful research tool.Directly integrated with OpenOffice.org. Amazing how extensions can make things happen.
