The series consists of copies of files of lot indexes created between 1973 and 1983 by the Legal Surveys Division of the Surveys and Land Records Branch of the Ministry of Lands, Parks and Housing and its predecessor body, the Surveys and Mapping Branch of the Department of Lands, Forest and Water Resources.
The files are arranged by land districts, with two duotang indexes for each district. Each file contains index information based on the National Topographic System (NTS) of map numbering. The index gives the location of every district lot within an area measuring 7 minutes and 30 seconds in both latitude and longitude. Each file also contains a map of each land district, overlayed by the NTS.
The first set of indexes, in black duotangs, were created between 1973 and 1975 and the second set, in red duotangs, were created between 1977 and 1983. The indexes were updated by the branch annually to show newly created lots and could be used with Departmental Reference maps that had been gridded with the NTS breakdown.
