This chapter considers several aspects of the material embodiment of the Prayer Book in paper and ink. The topics range from general questions, such as identifying the sequence of words that constitute the Book of Common Prayer and how their integrity is maintained, to details such as orthography, punctuation, editorial updates, the use of red ink and blackletter type, printers’ interventions, and the curiously named Black Rubric. The chapter also touches on nonverbal features of Prayer Books as books, such as typography, and design. Included are a number of examples of illustrations, unofficially added to various editions, which both interpret the printed text and indicate how it was understood.
