IP Authentication

It is possible to control your access to 123Library by IP. Users who come immediately from a specified IP address or IP range will be automatically logged in to your 123Library account.

Such users will be anonymous unless they either have a personalisation cookie or until they login to their personalised account.

It is important that you give us the external IP address (or IP address range) for your institution, and not the internal IP addresses used at your campus. If in doubt, please visit the following URL which will tell you the IP address that 123Library sees as your current external IP address: https://www.123library.org/ip-check/
