The first time you click on the UpToDate link, you will need to register for an account, or link your existing account to Augsburg's subscription. You'll see this screen:![UpToDate Registration Page](//libapps.s3.amazonaws.com/accounts/5210/images/UTDregistration.png)
Once you've registered, you can use UpToDate on your phone or tablet by logging in with the account that you create here.
