RefWorks also has different arrangements for Macs & PC. When you first open RefWorks, you'll see the links for each operating system. No need to visit another page. You will have access to your RefWorks account after you leave UGA.
To begin, here's the overview of RefWorks. This video has multiple segments, and it's worth the time to view all of them.
After you create an account, go to the Tool Bar and download "Tools". This is required to make the magic happen.
If you're given on option of using the orange version or the blue version of RefWorks, choose the blue version. This is newer and is replacing the orange version.
