How can I get started?
Zotero icons in the Firefox browser include the Z (to open up the Zotero database), the capture icon, and the down arrow to save the entire web page as a Zotero database entry.
When I've found an entry in a database (such as JStor) or the library catalog, the middle icon changes. In this example, I've found an article in JStor, so the icon has changed to a paper.
What happens when I click on that paper icon?
If you look at your Zotero database (also called library), you'll see the article listed. Click on the icon beside the citation, and you'll see the full text was saved as well.
Assuming you've installed the Word plugin, you can bring up the Zotero options under the Add-Ins tab at the top of the screen (Word for PC) or under the AppleScript icon (Word for Mac).
When you're ready to insert a citation, choose the first icon in the toolbar, and the very first time, you'll be prompted for which style guide for your document. Choose accordingly, and then you can search your database for the item you wish to cite.
Here I've searched for the madrigal article.
