On December 9, 2013, RefWorks will no longer require the Group Code when you log in from off-campus. (Write 'N Cite will continue to require the Group Code until a later upgrade.) For full details see RefWorks' announcement.
If you already have an account, you will simply log in.
You have to use an on-campus computer to set up an account for the first time, however.
CBU provides RefWorks to students, faculty, staff and alumni.
