Major publishing centres, principally Livorno, and later Vienna, would produce standard "Sephardic" prayer books suitable for use in all communities, and particular communities such as the Syrians would order these in bulk, preserving any special usages by oral tradition. (For example, Ḥacham Abraham Ḥamwi of Aleppo commissioned a series of prayer-books from Livorno, which were printed in 1878, but even these were "pan-Sephardic" in character, though they contained some notes about the specific "minhag Aram Tsoba".) As details of the oral tradition faded from memory, the liturgy in use came ever nearer to the "Livorno" standard.
