מחזור לראש השנה Majzor para Rosh haShanah (1968) is a bilingual Hebrew-Spanish prayerbook for Rosh haShanah compiled and translated by Rabbi Marcos Edery z”l, and published by the World Council of [Conservative/Masorti] Synagogues under the supervision of Rabbi Marshall T. Meyer (1930-1993). Earlier prayerbooks represented the Ashkenazi liturgical tradition. This is the first siddur that we are aware of for Sepharadi congreations in the Conservative movement. Besides the liturgy (in the Ashkenazi nusaḥ), the prayerbook is prefaced by Seliḥot and includes essays concerning prayer by 20th century scholars in Spanish translation. . . .
