Extras
As well as the main story, the book also contains a few extras. These include:
- a board game called Peril of the Pole, mentioned in the story
- a newspaper article written by Oskar Siggurdson that offers a different spin on the events. It describes Lee and Iorek as villains and mentions that the incidents in Novy Odense merely serve to re-inforce Ivan Dimitrovich Poliakov's belief as to the dangers of the bears.
- two pages from The Elements of Aerial Navigation, a book that Lee won with the balloon and which he uses to help him fly. Lee only has the first half of the book.
- a page from a book called The Shipping World Year Book, which includes an entry about Novy Odense.
- two letters written by Lyra Silvertongue from St Sophia's College, Oxford. She addresses one to Tom, the other to a Dr. Polstead: both concern Lyra's dissertation for her M. Phil in Economic History, implying that she writes in her mid-twenties. Her dissertation has (one version) the title "Developments of patterns of trade in the European Arctic region with particular reference to independent balloon carriage (1950-1970)". In the first letter Lyra also mentions that she continues to study the alethiometer.
- the certificate for submission of Lyra's dissertation
