A concise preface explains the criteria used to include churches in the book and the process by which the entries were created. Descriptions of more than 75 churches make up the bulk of the volume.
Following the individual entries are tables presenting comparative names of the primates (rendered in transcriptions of their original languages); statistical information about the primates (most common names, longest reigns); and current hierarchs as of 2004, arranged by church, date of accession, and date of birth. A glossary, selected bibliography and general index complete the work.
