Accompanied by Offprint: Nachträge und Berichtigunen zu Jacob Levys Wörterbuch. Berlin, 1924. “Jacob Levy (1819-92) is widely regarded as the founder of modern critical rabbinic lexicography and his dictionary had a tremendous influence on subsequent scholarship. In particular, Levy is credited with promoting the importance of the study of Syriac for determining the correct reading and/or etymology of a given word.” See www.library.upenn.edu/exhibits/cajs/jastrow/10.html.
