When a link that should connect you to an article takes you instead to a journal home page, this is normally due to the supply of incorrect metadata by the publisher to our link resolver and discovery system. It can also be caused by the linking not being set at the correct level (so instead of it being set at the article level it is set at the level of the journal title). We are not always aware of this problem occurring until you report it to us. Please tell us if you encounter this problem so that we can get it fixed urgently. Write to: ejournals@lib.cam.ac.uk or use the Report a problem form.
