Retired members, who are in receipt of their Cambridge University pension and have an active University IT account may continue to use it the normal way.
In regards to retired members of staff, wishing to use a University IT account to access eresources, the following statement may apply.
The licence terms under which we are authorising use of online services still generally exclude retired members of an institution as a group. We would extend the definition of "current staff or student" to include a retired academic who remains active within the department or College and therefore whose use can legitimately be seen as being for University purposes. We would require some form of communication, be that letter or email, from the faculty/college to that effect.
If in doubt or if you require further support and advice, please contact the eresources helpdesk at eresources@lib.cam.ac.uk
