Zotero has a bright future
Zotero, yet another electronic referencing assistant, gives us more freedom on easing people during creation of scientific paper.
Zotero is a Open Source, works through net, cites while online, and has good credentials with regard to working on cross operating systems as well as Office systems. It can also provide online synchronization, which means you dont even have to bring the citation with you!
The University of Mulawarman provides me a webdav page, so I can put my files on the network. However, if you dont have an access to any webdav server, you may still use Zotero webdav page (version 2.0b7.2).
The database can be exported to RefMan, Endnote seamlessly.
Best of all, it is free and easily installable on Mozilla Firefox.
