The two volumes of Prayer Book Parallels are aids to the study of the development of the American book from as many points of view as possible. They include liturgical texts and related historical documents. Volume One contains the texts of the public services of the American Church arranged in parallel columns--from the colonial period to the present--to enable comparative study. The two volumes are of great value to seminarians, clergy, church historians, and anyone interested in the development of the present Prayer Book.
