Each course has a reading list approved by the Department Board. The required reading is usually revised before each time the course is given and this is done two months before the course starts. The list is posted on the course web page. Parts of the required reading can sometimes be replaced at short notice, e.g. because a certain title is out of print. Buy nothing before the course introduction without first contacting the course coordinator.
The works can usually be purchased in Akademibokhandeln bookstore in Allhuset, second-hand in the Campus shop in Allhuset, in the student office in room X326 or from the lecturer. Parts of the required reading can also be found in other bookstores. Much can usually be borrowed at the Stockholm University Library; in the Frescati (main) Library.
