Semites and Anti-Semites: an Inquiry Into Conflict and Prejudice by Bernard Lewis.
A concise overview of the history and practice of anti-Semitism, including the nature of anti-Semitism in Europe, the somewhat nonsensical meaning of the word "Semite" (and its coinage, along with "anti-Semite," by a social Darwinist in an attempt to put a "scientific" gloss on Jew-hating), the traditional position of and attitudes towards Jews in Islamic civilization, the importation and flowering of European-style anti-Semitism in the Middle East at the time of the creation of Israel and the end of WWII, and some notes on distinguishing anti-Semitism from anti-Zionism in the current discourse on the Israel/Palestine issue. Extremely useful for anyone trying to follow this discourse in the media and academia.
