Just found a terrific book for my master's thesis topic -- it's a dissertation out of Uppsala, in English, called The Visible Wall. Written in 1998, it analyses the portrayal of Jews in Swedish cinema from the 1910's to the present-day. Since Jews are one of the few long-standing minorities in Sweden, the study provide some much-needed historical comparisons for the work I want to do on more recent immigrants and their depiction on the page and screen.
(The title is a reference to a 1944 film, Den osynliga muren [The Invisible Wall], made during WWII and depicting the plight of Jews in lands under German occupation.)
