From the post:
We think Zotero is the best tool for almost anyone doing serious research, but we know that a lot of people — including many students — don’t need all of Zotero’s power just to create the occasional bibliography. Today, we’re introducing ZoteroBib, a free service to help people quickly create perfect bibliographies. Powered by the same technology behind Zotero, ZoteroBib lets you seamlessly add items from across the web — using Zotero’s unmatched metadata extraction abilities — and generate bibliographies in more than 9,000 citation styles. There’s no software to install or account to create, and it works on any device, including tablets and phones. Your bibliography is stored right on your device — in your browser’s local storage — unless you create a version to share or load elsewhere, so your data remains entirely under your control.
