מחזור ליום כיפור Majzor para Iom Kipur (1969) is a bilingual Hebrew-Spanish prayerbook for Rosh haShanah compiled and translated by Rabbi Mordechai Edery (1928-2010) and published by the World Council of [Conservative/Masorti] Synagogues under the supervision of Rabbi Marshall T. Meyer (1930-1993). The Hebrew sourcetext is based primarily on the S&P siddurim compiled and translated by Rabbi Dr. David de Sola Pool. Other prayerbooks prepared with the Conservative movement represented mainly the Ashkenazi liturgical tradition. This maḥzor and its companion volume for Rosh haShanah are the only prayerbooks prepared for Sefaradi congregations by Conservative movement institutions (that we know of).
