Sha’arei Ephraim is a practical guide to the laws of public Torah reading by Rabbi Ephraim Zalman Margoliot, a respected halakhic authority of 18th–19th-century Galicia. The work is intended to facilitate study by community rabbis, who the author stresses should strive for full expertise in all areas of practical Jewish law, and to serve as a quick reference when a question arises during services and requires an immediate answer. It has become a widely accepted and relied-upon text, with many editions printed over the years, including translations and supplementary material by later scholars.
