The vast majority of these "towers" are in England and Wales but the guide includes towers from the rest of the British Isles as well as a few from around the world (including the United States, Australia, Canada, Africa and New Zealand).
Previously the location of rings of bells was a matter only of local knowledge and hearsay.
Dove produced eight editions of his guide between 1950 and 1994, managing to visit and ring at nearly all the ringable towers himself (a never-ending task as rings are continually added, removed or upgraded and, at least in the Guide's early years, rediscovered).
After 1994, he handed over responsibility for the Guide to the Central Council of Church Bell Ringers.
Entries in the Guide traditionally listed the town or village, the county (or country), the dedication (saint) of the church, the number of bells, the weight of the tenor (the largest bell) and its musical note, and the tower's usual practice night.
