In 1989 the Geological Survey of Greenland (GGU) increased its publication range by the introduction of an Open File Series, the aim of which was to speed up the presentation of new information to industry (Ghisler, 1990). This unedited series presents primarily raw data (field and analytical results) allowing exploration companies to use the information in assessment and planning. Although the series was formalised in 1989, a handful of reports of specific relevance to mineral exploration, and released by GGU up to three years previously, were numbered as the first six titles of the series. At the end of 1992, 40 reports made up the series.
