This volume serves as a comprehensive biographical and administrative record of the clergy within the Church of England for the period of 1977 to 1979. Compiled by the editorial staff at Oxford University Press, this directory functions as a primary reference tool for tracking ecclesiastical appointments, ordinations, and career histories of ordained ministers during the late twentieth century. It provides a structured data set intended for researchers, church administrators, and historians interested in the institutional structure of the Anglican Church.

Experts and historians frequently cite Crockford's Clerical Directory as the definitive authority for verifying the professional history of Anglican clergy. Researchers note the high density of factual data, which makes it a foundational resource for genealogical and institutional studies within the Church of England.
