The login screen for RefWorks and Write-n-Cite offers an option to login with a Group Code.
You don't need the Group Code for RefWorks or Write-n-Cite if you have set up your browser for off-campus access. Setting up your browser for off-campus access also gives you access to all the libraries' subscription databases, journals, and ebooks.
If you choose to not set up your browser for off-campus access, the Group Code will let you into RefWorks from off-campus without going through the proxy server. When you sign up for a RefWorks account, you receive an email stating your username, password, and the Group Code. If you forget any of these pieces of info, you can choose "Forgot your log-in?" from the RefWorks login screen. RefWorks will send you an email stating your username, password, and the Group Code.
