This study aims to determine the capabilities of GIS in mapping of library performance indicators at Tehran University of medical sciences and Shahid Beheshti University of medical sciences.
The descriptive research method was used to carry out this research. All central and college libraries in Tehran university of medical sciences and Shahid Beheshti university of medical sciences were selected in sampling. Selected six performance indicators in this study cover broad categories in the library various fields such as: facilities, staff, collections, and expenditures, that required data for calculating them gathered with questionnaire. Finally the data analysis was conducted using ArcGIS version 9.3.
Findings: ArcGIS software has capability of displaying performance indicators in the format clear images to conduct suitable analysis, in other words displaying these indicators in the form of graphs and tables not only makes analyzing difficult but also it is lacks the precision and generalization.
The maps applied for performance indicator analysis with GIS, like a road map to guide people according to their needs and respond to various questions, so they can extract much analysis from these maps; in addition, data analysis is just one of the GIS capabilities among the numerous capabilities

This research aimed to evaluate the status of international scientific journals. The study population was a collection of the publications of Journal Citation Reports (JCR) published by the Institute for Scientific Information (ISI) in 2005 which is more than 6,088 journals. This paper explains the differences between the journals of the study population and journals of ISI. It then investigatespublishers, the status of scholarly papers and review articles, impression, range of the papers, impact factor and immediacy index of the journals assessed. The research showed that 30 percent of the journals of JCR belongs to the United States of America then follows England (21%), the Netherlands (9%) and Germany (7%). The impact factor of half of the journals is between 0 to 1 and 75% of the journals have an impact factor of 0 to 2. Immediacy index of 94% of the journals is between 0 to 1. The number of papers of the scholarly journals doesn’t follow a special standard. 3% of all the documents include review articles. English is the most frequently used language and.65% of the journals of JCR belong to 79 publishers

After the conquest of Iran by the Arabs, the rulers faced the administrative question of recognition of the conquered lands and clearly mapping the roads and villages. For this reason, historical geography developed from the third century onwards. Muslim explorers and geographers successfully collected relevant information by either personal observation or by asking travelers from both near and distant parts of the Islamic world, and finally created valuable written works on this subject. These writings, created continuously from the 3rd century to the 8th century, are collected in ten books in which one can trace the trend of development and evolution of a city or a region. In this article, we have examined pictures and reports related to city/region of Esfahan by referring to sixteen works on historical geography (from the 3rd century until the 8th century) and have traced the trend of development and movement of city/region of Esfahan. It is worth saying that the evolution traces both human and natural geography.
