The Jewish Year Book 2005 provides a comprehensive directory of the communal institutions and organizations that make up the fabric of British Jewish society. It is a guide to the structures and networks of the religious, social, educational, cultural and welfare organizations of the Jewish community across the British Isles and reports the ever-changing pattern of websites, now such a pervasive feature of communal management and presentation. It also offers an extensive guide to the primary organizations of the Jewish communities of the world and a substantial survey of Israel and its organizations that have associations with British Jewry, including a comprehensive list of Israel's overseas embassies and missions. It sets out the basic facts of the history of Jewish settlement in Britain and an up-to-date statement of UK legislation specifically concerned with the place of the Jews and Jewish identity in Britain. Updated annually and edited to provide the latest information, it includes contact details for Jewish institutions, local and international organizations, details on leading Jewish personalities, obituaries and major events as well as principal festivals and fasts. There is also a detailed calendar, including the Jewish calendar for thirty years and evening twilight regional variations.
