This series contains 31 notebooks with a combination of notes taken from primary and secondary sources and first-hand observations of churches across England, Wales, Scotland, Ireland and Central Europe, arranged alphabetically by county or town as indexed. They are predominately descriptions of Anglican and Roman Catholic churches but also contain descriptions of other Christian denominations and churches of other faiths.
Each volume contains written notes on the recto of each folio and newspaper cuttings, photographs, etc. glued to the verso. Volumes are foliated, and churches given running numbers (the numerical sequence being revised in 1932).
