I hope I am not repeating previous suggestions, but the most useful "general" text I have found is Mary Douglas's "Purity and Taboo" which covers broad notions of prejudice and such from an anthropological viewpoint, including anti-Semitism. Sander Gilman has also done some interesting work on general notions of stereotypes, of race or sexuality, in two of his books: "Difference and Pathology: Stereotypes of Sexuality, Race and Madness" as well as "Freud, Race and Gender". They focus (obviously) on 19th and early 20th century Europe, but he gives a careful analysis of anti-Semitic discourse in Germanic and Slavic history. Neither are studies of medieval phenomena, but Douglas at least has been cited by many working in medieval fields. Regards, Terry %%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
