In this collection of essays written over some 40 years, Soloveitchik (Yeshiva U., New York) expounds on the dynamic nature of halakhah (Jewish law). He focuses on forces that shaped halakhic
observance. The first section consists of a survey and characterization of the influential medieval rabbis Rashi and the Tosafists. Subsequent sections present in-depth studies of ribbit
(usary) and yein nesekh (wine made/touched by Gentiles). The book includes a bibliography of manuscripts with their original catalogue number at the Institute of Microfilmed Hebrew Manuscripts,
National Library of Israel. Distributed in the US by ISBS. Annotation ©2013 Book News, Inc., Portland, OR (booknews.com)
