Your University IT account will only work with eresources and content for which the University actually holds a current licence.
To establish which resources these are you should go through iDiscover the Databases A-Z as these will confirm what we have access to and provide information regarding dates of coverage and access routes. If you are a current member of staff or a current student it is not essential that you login to iDiscover first.
Should you find you can't access something, that you should be able to and your University IT account is working fine then please contact eresources@lib.cam.ac.uk
