Some societies make special arrangements for their members to have access to the full text of society journals. If you are a member of such a society, you will need to activate your subscription on Cambridge Journals Online in order to get access to the society's journal(s). To do this, you need to have registered with Cambridge Journals Online and you need two pieces of additional information: the Society ID (the society's Cambridge Journals Online unique identifier) and the Society Subscription ID (your membership number). These should be sent to you by the society.
To activate your society subscription make sure you are logged in, then click on the 'Activate Subscriptions' link in the 'My CJO links' drop-down menu at the top left-hand side of each page, immediately below your log-in details. Halfway down the 'Activate Subscriptions' page you will see 'Society Subscriptions'. Enter the Society ID and Society Subscription ID and click 'Activate'.
