Government Gazettes are a neglected source for the colonial history of Africa, and it may be worthwhile to draw attention to various types of information to be found in those for Northern Rhodesia, which have recently been made available on microfilm. Up to 1911 the British South Africa Company administered two territories north of the Zambezi: North-Eastern Rhodesia and North-Western Rhodesia. For North-Eastern Rhodesia the Company published at Fort Jameson (now Chipata) a monthly Government Gazette from 1903 to 1911. There was no Gazette for North-Western Rhodesia; legislation for this territory was initially published in the Official Gazette of the High Commissioner for South Africa, though some relevant proclamations and government notices were reprinted in the North-Eastern Rhodesia Gazette . From 1911 the Company published a Government Gazette for the amalgamated territory of Northern Rhodesia; the frequency varied between twelve and twenty issues a year. In 1924 the Colonial Office took over responsibility for Northern Rhodesia. Thereafter the frequency of publication tended to increase, reflecting the growth of government, business, and white settlement. Before 1939 it ranged between 24 and 50 issues a year, and from 1939 to independence in 1964, between 50 and 80 a year.
