When you log into your RefWorks account, you'll notice that a new RefWorks 2.0 button/link has been added to the main toolbar:
RefWorks 2.0 is a new, user-friendly interface that functions the same way as the current iteration (now branded as "RefWorks Classic").
If you currently have a RefWorks account, you have the option to upgrade your account to the new 2.0 version by clicking the link in the upper-right corner of your RefWorks page that you see illustrated above.
All RefWorks accounts will default to the 2.0 interface by the start of the fall semester.
Current account holders will have until the end of 2011 to upgrade their account to the new version.
