The individual letters within the files had alphabetical classifications written onto them and order within the files was alphabetical. This series therefore reflects the alphabetical arrangement for the subject files in FEBR 3 for the years 1966-72, though some classifications - for example "Capital Punishment" - do not occur in FEBR 3. There are also inconsistencies: both Ireland and Northern Ireland occur, while all Middle East records (including CAABU, the Council for Arab-British Understanding) have been classified as Jordan. The sequence is also incomplete, as files exist only for C-K and P-Z.
