And bear in mind that Vulcan 607 is about the Vulcan's part in the Falkland's war - to learn more about the Vulcan your Dad would have known (the Vulcan that was at the tip of Britain's nuclear deterrent spear), I'd recommend 'Bombers of the West' by Bill Gunston (it's beautifully written and not too laden down with detail, so is ideal for the lay reader, but can only be found second hand) and even the mammoth HMSO tome on RAF nuclear deterrent forces.
If you were an enthusiast, I'd probably recommend PPRuNer Tim McLelland's book on the Vulcan, or his V-Force tome (published under the name Tim Laming), but you might find Robert Jackson's Modern Combat Aircraft 11: V-Bombers to be a better start.
My own Vulcan book is still a work in progress - though it will feature an illustration of your Dad's old aircraft, and of a number of No.IX Squadron Vulcans that would be in his log book.
