The records were deposited on loan on the understanding that the company has first sight of any work which makes extensive use of them. There are certain restrictions on the use of the staff records which are more stringent than the normal thirty-year rule for business records. The Secretary has retained the principal statutory records, such as the minutes of the main board, although these may be consulted by arrangement with the Company Librarian.

The printed, twice-yearly, 'Reports from the Directors to the Proprietors' or shareholders are complete, 1840 to date. The accounting records include: the schedules to the annual accounts, which contain the basic information for the trading position of the company, 1856 to 1878 and 1905 to 1961.

Journals (a daily record of transactions) have been kept in a similar sample; they are complete from 1842 to 1851, and then exist only from 1859 to 1861, 1869 to 1870, etc until 1930 to 1932.

Import and export freight ledgers survive for the years 1940 to 1957. The internal economy and working of the company are presented in detail in the Annual Departmental and Agents' Reports, 1893 to 1970. The Agents' Reports commence in 1905.
