To create an account:
If your email domain matches more than one campus or school, a dropdown displays. Select the appropriate institution to continue.
If you have a TDM Studio workbench or a My Research account you need to register that email address to access the visualizations, but you will not be prompted for a password. Use your existing password when you login to the visualizations.
ProQuest will send you a verification email. Open the URL in that email. A page confirming that your email address has been verified displays. From here, there is a link to log in to TDM Studio.
