To start collecting material, you first need to install the Zotero Connector in the browser of your choice.
Zotero usually senses when you are looking at an article in a subscription database, or an online source like the New York Times, or at a book in the RRU Discovery search tool When it does, you can add the citation to your Zotero library. Where and how the Zotero connector shows up will depend on what browser you're using, how many other extensions you have installed, and what type of document(s) you're looking at. Usually, it will look like a Z, a page icon, or a book icon. It might also be hidden in a larger Extensions menu (looks like a puzzle piece). Here's where mine is in Chrome. Have a hunt around until you find yours.
You can click that icon on any page on the Internet and Zotero will do its best to grab available metadata and create a citation record in your Zotero library. Obviously, this works best when the page you're looking at is related in some way to a book, article, or other reference item, but you can also grab citation information for websites and webpages.
It is useful to double check the completeness of the citations you import as you capture them. If a citation element is missing in the record, for example, the volume and issue numbers, Zotero will not be able to generate a complete citation in your bibliography.
One citation at a time
In many of the article databases, you can auto-capture one citation at a time. If you see an icon like the one circled here in red, click on it and Zotero will capture the citation and attach the full text of the article as well if it is available.
Articles:
When you have a list of search results in Google Scholar or in a database platform such as ProQuest, EBSCO, or JSTOR you will see a folder icon in the upper right corner of your browser, next to the 'Z'. When you click on that folder icon you are able to select the article citations you want to save to your Zotero library. When you click on the 'OK' button, those items are added to your Zotero library.
This captures the citation information as well as a links if they are available, but not the full text. If you want to collect full-text article PDFs directly in your Zotero library, you'll need to grab your citations one-at-a-time.

Collecting Websites
Zotero allows you to auto-save the citation information for some websites. These pages can be idetified by the icon of the piece of paper at the end of the URL window. If you find a webpage without this icon, try installing Readability, a free Firefox add-on that strips away unnecessary web content to let you focus on the text. According to this ProfHacker article, installing the Readability app makes sites that weren't interpreted by Zotero able to be captured via the Zotero icon in the address bar.
Your browser plugin for Zotero may offer to add a proxy address to articles and books you find. You do not want this. To turn it off, click on the 'Proxy settings' link...
and disable the proxy in your browser
If you do not see that yellow bar across the top of your browser but you are still having trouble, right click on the Zotero shortcut in your browser and choose, ‘Manage Extension’ or 'extension options'.
