Earlier annual reports of the Colonial Geological Surveys and Overseas Geological Surveys were published as articles in various issues of Colonial Geology and Mineral Resources and Overseas Geology and Mineral Resources respectively. This series of stand alone annual reports began covering the years 1957-58 and published 1959 and continued to cover the year 1964 and published 1965. In 1965 the Overseas Geological Survey was subsumed into the newly formed Institute of Geological Sciences and the annual report was issued as part of the IGS annual report.
