Zotero: Firefox as Reference Manager
Zotero is still under development and not quite ready for a full review, but it is definitely worth a look. Zotero is a Firefox plugin which retrieves text snippets, websites and bibliographical records from the currently shown webpage and stores them in a searchable database which is managed and accessible through the internet browser. For example you can do a normal search at an online library and import the results comfortably into your database with a simple click on a button in the browser's location bar. It also works with selected journal sites, where you can even download attached PDF-articles if available. Then you can export your references into one of the popular bibliographic formats for use in other applications. At this stage Zotero's citation-insertion capabilities are still quite rudimental and only available for Word, and therefore the software cannot yet fully replace any of the full-featured bibliography tools. This might change soon; Zotero is an ambitious open-source project with a very promising software architecture and developers' support. Once this one is grown-up it will be beautiful - and best of all: free! Keep an eye on it...
