If you can access your email and Moodle there may be a problem with your library account.
Email the E-Access Team (e-access@city.ac.uk) and we will investigate the problem.
Make sure you provide your details and the details of the resources you are trying to access. A screenshot of the error message is really helpful too.
If your City username and password do not enable access to email or Moodle then you should contact the IT Service Desk:
