The Second World War subject files belong to the Confidential Office file series and are arranged according to their Confidential Office subject file number (28). Each individual file reference consists of the subject number '28' followed by an oblique stroke and a unique, sequential file number, for example: file 28/5. This file number is further subdivided, if another part file on the same topic was created, for example: file 22/5 II. The Roman numeral 'II' represents file part '2'. Some files are further subdivided using letters, for example file 28/1 is followed by 28/1 A, through to 28/1 W. Some of these files are further subdivided into parts indicated as Roman numerals, for example 28/1 K is divided into three parts (I–III). Gaps in the various sequences described above indicate missing or weeded files.
