Book excerpt: The Routledge Handbook of Judaism in the 21st Century is a cutting-edge volume that addresses central questions and issues animating Judaism, Jewish identity, and Jewish society in a global, integrated, and forward-looking way. It introduces readers to the complexity of Judaism as it has developed and continues to develop throughout the 21st century through the prism of three contemporary sets of issues: identities and geographies; structures and power; and knowledge and performances. Within these sections, international contributors examine central issues, topics, and debates, including: individual and collective identity; globalization and localization; Jewish demography; diversity, denominations, and pluralism; interreligious relations; political orientations; community organization; family and gender; the Bible and Talmud today; Jewish philosophy and authority in Jewish thought; digital Judaism; antisemitism; Jewish spirituality and rituals; memory; language; religious education; material culture, literature, music, and art; approaches to the environment; and contemporary Zionism and Israel. The handbook also includes an extensive bibliography to help orient readers to the most important and leading work in the field. The Routledge Handbook of Judaism in the 21st Century is essential reading for students and researchers in religious studies and Jewish studies. It will also be useful for those in related fields, such as cultural studies, literature, sociology, anthropology, and history, as well as Jewish professionals and lay leaders.
