Please remember, citations from Zotero are machine generated and could contain errors. Always double check citations against the style manual you are using. If you need help formatting citations, feel free to contact the library.
First, you're going to need to download Zotero from www.zotero.org. You should first download the desktop application and then add the browser extension to your preferred browser(s).
If you are planning to use Zotero with a word processor such as Microsoft Word, the necessary plugins should be automatically installed when you install the Zotero desktop application. If you are using Google Docs as your word processor, the browser plugin will add Zotero functionality to your Google Docs.
After you install the Zotero desktop app and the Zotero Connector, you will need to set up your preferences to allow for syncing and cloud storage of your citations. The first step is to register for a free Zotero account. You can do this on the Zotero website.
Once you have created an account, you can return to the desktop application and sign in. To do this, select Preferences under the toolbar tab Edit (on a Mac, select Preferences under the Zotero tab on the menu bar).
Next click on the Sync tab of the Preferences window. Enter in your username and password to your account and select both the Sync Automatically option and Sync Full-Text Content option.
If you would like to be able to access the attached files remotely, then select the Sync attachment files in My Library using Zotero. Currently, Zotero gives all users 300MB of storage for free. Additional storage can be purchased on their website; however, other citation management systems such as EndNote offer more functionality if you are going to pay for the service. Most PDFs range in size from 100KB to 1MB, so Zotero's free storage can hold between 300 and 1,200 PDFs, depending on the size of the PDFs
To access the stand-alone client (the desktop app) on your computer, open it from the programs menu. If you have not yet added the Zotero connector for your browser, you can do so from the Download Webpage.
