Zotero 6.0 is the current version of Zotero. It's a standalone program, or "client," not a browser extension.

If you'd like to use Zotero with other browsers or on mobile, you'll need the Zotero Bookmarklet.
Open up Zotero and go to Edit → Preferences to make some basic modifications to Zotero's functionality.
You may also want to modify the size of the standard display font. To make this change, go to View → Font Size.
Zotero offers a Lookup tool to help you get to the full-text of articles for which you have only a citation in Zotero. Located near the top right of the Zotero client, it looks like a green arrow pointing to the right. The lookup drop-down menu includes Google Scholar and CrossRef by default, but you can add our library's full-text linking, too. This works just like the Get It @ UMassD button in our library databases.
Under "OpenURL," in the "Resolver:" box, paste this link:
Now click "OK" at the bottom to save your settings.
One of the best features of Zotero is the way it automatically pulls in digital files, such as PDFs. Zotero offers 300 MB of free storage; after that, they have a tiered pricing plan.
Zotero strongly recommends you backup your data in addition to syncing it.
