The Incorporated Church Building Society records in Lambeth Palace Library comprise over 15,000 files relating to applications for grants from the Society between 1818 and 1982. The files may include application forms, correspondence, plans, building specifications, engravings or artists' impressions, certificates of the satisfactory completion of the building project, parochial subscription lists, parish magazines, and, from 1867 onwards, photographs.
The Library has a series of minute books, 1818-1989, numbered 1-36, and additional volumes, numbered 37-42, including an additional volume recording the foundation of the Society. The volumes record the proceedings of the ICBS committees and its Annual General Meetings.
Note that files for some of the applications have not survived and these are marked as MISSING in the catalogue record for that reference, although evidence for the application may survive in related entries in the minute books. Other numbers are simply skipped in the numbering sequence.
