Introduction
The Iranian Research Institute for Information Science and Technology (IRANDOC) is an institute affiliated with the Ministry of Science, Research, and Technology (MSRT) which was established to work in the field of science and technology of information and librarianship. The institute enjoys total independence and according to the articles of association, its activities consist of information research, collecting and dissemination of scientific information and documentation for the purpose of meeting the information needs in this area and undertaking the development of a scientific information network. To achieve this goal, this institute has so far developed various scientific databases and meets different information needs of its users. At present, the Scientific Information database of the institute with more than 615,000 information records, 126,847 of which belongs to the graduates' theses, has on the average more than 22,000 visitors daily, and according to the report of the High Council of Information, the database ranks first in terms of content and quantity amongst the governmental sites of the country.
The geographic information system (GIS) as a decision support system has been able to greatly contribute to the optimal decision-making of analysts and managers by taking advantage of new technologies and related specialties. The wide range of GIS and its benefits confirm this success. Today, among various areas of utilizing spatial information system, use of GIS to collect, analyze and present information has a special position, because all human activities are essentially current in the context of the time and place. With this approach and to evaluate and spatially analyze scientific products existing in the Irandoc library databases, examining how to use GIS is the main issue of this research, considering numerous features of this technology. All attribute and spatial data related to geospatial theses of the library's database were extracted, sorted, controlled, classified and encoded before being input into the ArcMap program (ArcMap is the main component of Esri's ArcGIS suite of geospatial processing programs, and it is used primarily to view, edit, create, and analyze geospatial data. ArcMap allows the user to explore data within a data set, symbolize features accordingly, and create maps).
In this study, by using the ArcMAp program, in addition to quick and correct access to the data required in abundant volume,...
