If you buy your subscription directly through Cambridge Journals Online your subscription will be activated for you and there is no need for you to take any further action.
However, if you have purchased a subscription in any other way (through a subscription agent, for example, or by mailing a cheque to Cambridge University Press) you will have to activate your subscription in order to get online access to the full text of articles.
To do this, you will need to be registered with Cambridge Journals Online and have logged in. Look for a link to 'Activate Subscriptions' in the 'My CJO Links' menu which appears at the top left-hand side of every page. Clicking on 'Activate Subscriptions' will take you to a new page. Enter your subscriber number (see below) into the 'Subscriber Number' box, then click 'Activate'. To activate multiple subscription numbers, enter all your subscriber numbers, separated by a comma, into the text area and then click 'Activate multiple'.
If our Customer Services department has your email address they will email you the subscriber number when you subscribe; otherwise they will mail it to you. If you are subscribing to the print as well as the online version of the journal, you will also find your subscriber number on the carrier sheet in the journal package.
If your subscription originates from the UK, your subscriber number will be a 6 digit number. In North America, the subscriber number is either an 8 or 9 digit number.
