If you look through the handbook, next to the subjects there shuld be a description/recomended text books. Atleast thats how it was for pharmacy. Also if you log into myuni, clik on one of ur subjects and you shuld get details on your lecturer aswell as a booklist.
But i wuldnt buy anything yet =\. wait for the lecturers to give you the most suitable textbook reference (if any).
