Zotero 2.0

New Features

We are excited to announce the launch of Zotero 2.0, which introduces a powerful slate of new features, including:




Even More Functionality That Makes Your Life Easier

Upgrading from Zotero 1.0

Upgrading from Zotero 1.0 is easy: just click the Download button on the Zotero home page. After installation, Zotero will prompt you to convert your 1.0 database to the new format used by 2.0. To avoid any disappointments, please make sure to:

Don't want to upgrade now? If you've installed 2.0 but haven't yet upgraded your database, you can reinstall Zotero 1.0, but note that Zotero 1.0 is no longer supported and no longer receives translator or style updates.

Cancelled the upgrade wizard? Restart Firefox to continue the upgrade.

Word Processor Integration

Zotero 2.0 requires new versions of the word processor plugins, and documents used with 2.0 can no longer be used with Zotero 1.0.

Documents used with the Zotero 1.0 plugins must be refreshed and resaved with the Zotero 2.0 plugins on the same computer on which they were previously used with 1.0, and that Zotero database must then be used as the source for Zotero 2.0 syncing. If you first refresh them with a Zotero 2.0 plugin on a different, synced computer, you may end up with mismatched citations.

Zotero 2.0 does not work with Word X for Mac (from 2001).


To start syncing your library with the Zotero server, create a Zotero account and enter your username and password in the Sync tab of the Zotero preferences (you already have a Zotero account if you previously registered on the Zotero Forums).

As you now make changes to your library (add, edit, and delete items), those changes will be automatically synchronized with the Zotero server. The first time your Zotero library syncs, Firefox may appear to hang, especially if you have a large library. Please be patient.

Accessing Your Data from Other Computers

Once you have set up one computer to work with Zotero 2.0, you can access your library from any computer with Zotero 2.0 installed.

On another computer, install Zotero 2.0 and add your Zotero username and password information as indicated above.

Click the Zotero sync icon to initiate automatic synchronization of this computer with your Zotero account. As you make changes to your library (add, edit, and delete items), those changes will be automatically synchronized with the Zotero server.

Existing Data on Multiple Computers

If you have existing Zotero data on multiple computers, the standard sync process will merge that data together, creating duplicates of any items that exist on more than one computer. This applies even if you transferred a Zotero 1.0 library by copying the data directory to another computer.

To avoid duplicates, you'll need to use one of the sync reset options to force Zotero to overwrite data on one side.

Reporting Problems

All bugs should be reported in the forums.
