PSALTER. The word Psalter  is often used by ancient writers for the book of the Psalms, considered as a separate book of Holy Scripture; but the term is generally used now of the book in which the Psalms are arranged for the public service of the Church. The Roman Psalter, for instance, does not follow the course of the Psalms as in the Bible, but arranges them for the different services. The division of the Psalms into daily portions, as given in our Prayer Books, has been done with a view to convenience. The Psalter, properly speaking, is a separate book from that of Common Prayer. The English Psalter does not follow the last translation of the Bible (which is the authorized one), but that of Coverdale's Bible, corrected, which had become familiar to the people from constant use.
