Access to is authenticated using the following methods:

Institutional IP Address

To use Emerald’s e-resources institutions should obtain and use a fixed, external IP address. Why?

  • Access by IP is preferred - we can register both IPv4 and IPv6 protocols (if both are in operation at your institution, it is essential that both are registered to the account)
  • Instant recognition for institution
  • Seamless access, no need for log-in details (username / password)
  • Administration reduced as all computers networked on the IP address can access e-resources
  • Heightened security due to reduced misuse of log-in details (username / password

For these reasons we do not allow an IANA IP address to be registered for access - as per the list 
here. Please contact Emerald Customer Support for additional information


Emerald supports federated authentication through Shibboleth, OpenAthens or SAML 2.0 and is compliant with several major federations. For the current list please see our Shibboleth information page.

Organisation Access Number (OAN)

We are now able to provide Organization Access Numbers (OAN) to support off-campus access, where it isn't possible to use the alternative authentication methods which are referenced above. OAN's can also support membership access where username and passwords are preferred. Please contact your Regional Sales office or Customer Support for further information.
