I'm not entirely sure what you're trying to say, but for the record Annales is nominative plural, ie it's a subject.

There is no 'of' part in Annales, nor should there be. Nor is that dative; possession is genitive. But again the subject should be nominative, not sure what you mean by it switching.

The Mundi is in the genitive, since it's the world's annals.
