''The Colonial Office List''

From 1862, the Colonial Office published historical and statistical information concerning the United Kingdom's colonial dependencies in ''The Colonial Office List'', though between 1926 and 1940 it was known as ''The Dominions Office and Colonial Office List''. It later became known as the ''Commonwealth Relations Office Year Book'' and ''Commonwealth Office Year Book''. In addition to the official ''List'' published by the Colonial Office, an edited version was also produced by Waterlow and Sons. It can be difficult to distinguish between the two versions in library catalogue descriptions. For example, '' The Sydney Stock and Station Journal'' of 3 December 1915 commented:

First Colonial Office (1768–1782)
