Purpose: The purpose of this paper is to provide a report on the application of a Geographic Information System (GIS), ArcInfo, in the cataloguing of geosciences documents held by IRANDOC. Design/methodology/approach: The steps involved in the application are described: gathering the data and required input including the attribute and spatial information; pre-processing the information; managing and analysing the data; producing outputs. Findings: This research resulted in establishing a complete and comprehensive database of the geosciences, illustrating, analysing and reviewing all types of data available in the various databases of IRANDOC (geosciences related) simultaneously and easily. Research limitations/implications: Although this investigation concentrates on very specific documents (the geosciences documents held by IRANDOC), its findings and the presented model of the plan can be generalised to collections of information related to the spatial position in some other areas. Originality/value: In addition to quick and correct access to the data required in abundant volume, the spatial and subject data can be depicted in the forms of maps, tables and diagrams and also can be edited, updated and used in various ways. Also the way can be paved for identification and introduction of the various similar systems in different geographical areas.
