You should focus preparation on the principal texts to be studied on the course. You are required to buy the following:
Michel Foucault, History of Sexuality, vol. 1: The Will to Knowledge
Sigmund Freud, Civilization and Its Discontents*
Manuel Puig, Kiss of the Spider Woman
Sylvia Townsend Warner, Lolly Willowes
Ann Bannon, Beebo Brinker
Jeanette Winterson, Written on the Body
*The set edition of Civilization and its Discontents for the course is the Penguin text translated by David McLintock.
Rudyard Kipling's short story 'Mary Postgate' (1915) is collected in A Diversity of Creatures (1917). It is out of copyright and available in various e-reader formats and in HTML at Project Gutenberg. A high quality scan of the Macmillan Standard Edition of the volume - with the page numbers you will need to reference the story in an essay - can be found on Internet Archive (you can read the story online there or download the book in pdf format).
The rest of the reading on this module will be available via Blackboard.
