When using Chrome, it is important to make sure you have the standalone version installed on the computer you are using and that you are logged in to Zotero. The Chrome extension, unlike the Firefox Extensions, will not sync your citations without the standalone version installed, opened and logged into your account.
To get the Chrome Extension, you need to visit the Chrome Store via this link. Once there, search for Zotero and the first result should be for the Zotero extension, or you can click here to directly go to the Zotero extension in the Chrome Store.
Once you have found the Zotero Connector in the Chrome Store, click the blue "Add to Chrome" button on the right side of the screen across from the title Zotero Connector and it will be added to your Chrome installation. If you'd like to read more about it, click on the box and a popup window will open up that will allow you to view a full description, screenshots, reviews and more.
Now that the Zotero extension is installed, you can start clipping citations. To do this, simply go to a site, database, article via chrome and look at the top right corner of your address bar for an icon that Zotero can clip.
A box will appear at the bottom right corner of your browser that notifies you the content is currently being clipped. Once it finishes clipping the article and citation, it will disappear. To check and make sure the article clipped, all you need to do is open the standalone client and take a look. It should sync automatically to your desktop. In this case, we clipped the article called "America's Star Libraries, 2015: Top-Rated Libraries," and as you can see, it is in our standalone version.
To the right of the title, you can see all the detailed citation information for the article you just clipped. The Zotero Connector will grab as much citation information as is provided by the website you are visiting. You can always add additional information if it is missing or incorrect.
Another feature to take note of is the fact that the Zotero Connector also clips the article or a snapshot of the website. If a PDF is available, it will clip the PDF. If it is a webpage, it will take a snapshot of the webpage. This can be seen in the standalone version by clicking on the title of the citation and seeing the files attached.
