Overall, a useful guide to the ceremonies, traditions, protocol, and vestments of the Catholic Church. It includes many detailed descriptions of particular rituals and masses, special vestments and which individuals have the right to wear them, honors for lay and priests alike, protocol for events, proper addresses for members of the church hierarchy, and more. An interesting feature of the book is its detailed examination of changes, particularly in ritual and vestment, since the Second Vatican Council. Also included are many very beautiful color images and photos, fully captioned in a list of illustrations at the back of the book. This would be helpful as a reference text for those who work a lot with the Church hierarchy or who are often engaged in studies of or related to the Church. However I would not recommend this book for casual reading, and I would not recommend trying to read it cover-to-cover; there is far too much information to absorb and the material can be complicated at times, especially to the uninformed reader who will need to spend much time looking up terms on their own or flipping between the text and various images to try to get a sense of what they are reading about (terms for vestments, for example, are defined but often poorly-described and seem to be written with the assumption of a certain amount of base knowledge).
