Officially launched in 1999 by the Ministry of Sciences, Research and Technology, Ghadir Project provides direct access to academic libraries’ holdings. Patrons of member libraries could use the resources regardless of point of access. The present paper attempts to evaluate the project from the view point of its most important beneficiary, i.e. users located in Metro Tehran.On the average, 60 percent of the users based in Tehran, have assessed the impact of Ghadir Project as high. 71.2 percent were highly satisfied with the project. Users’s perception of the most outstanding limitations and possible issues with Ghadir Project were: Lack of either hardcopy or online union lists, lack of cooperation by some libraries, technological issues, discrimination between libraries’ in-house patrons and those referred by other libraries, low number of member libraries, big Libraries dissatisfaction with the additional workload, and bureaucratic red-tape. In several cases there had been significant differences in perception among three user groups (Graduate Students, PhD Candidates and Faculty Members).

The purpose of number group representation is to construct the permissible combinations of cardinal and ordinal numbers in Persian language. In this paper 38 members of the Persian enumeration system have been placed in four multi-member and two single member groups. The said 38 members were placed into two general rule groups (Rules applying to the cardinal number groups and ordinal number groups). There are 47 rules governing cardinal numbers while there are only four rules for ordinal numbers. Ordinal numbers are also of two types. An investigation into the potentials for superposition of ordinal and cardinal numbers is made and examples are offered.

Weblogs are simple internet-based pages and are a very recent phenomenon. They make accessible for a large group of users classified and searchable information. In effect they had provided an information forum whereby individuals can partake in discussions. Librarians were among the first to welcome this new development and using it to spread new ideas, opinion and information. Weblog importance lies in its simplicity of hassle-free operation. The librarians do not need to be adept in technical issues. At whatever ICT level of expertise, the librarians could deploy weblog to publicize their services, get in touch with colleagues and enhance their own knowledge. The present paper provides an overview of weblog phenomenon, the current research underway and its myriad of applications in the world of libraries and librarians.

The educational institution was among the early institutions undergoing radical changes with the dawn of the information age. Electronic Learning, as a new paradigm, has evolved this area. Given its potential, the shear volume of demand for education, and the ineffectuality of present educational system in addressing it, leaves no room for doubting both the necessity and importance of e-learning. What is at stake is the nature and mode of deployment of such learning. As a subsystem of the educational system, the libraries should keep pace with change and try to incorporate this new learning mode within their operational and service structure.

Distance learning is one of the issues pre-occupying the information society. Within this context the digital libraries are often deemed as one of the service points offering such services. This would require reference librarians to be up to more important and sensitive tasks. The present paper expounds on the various modes of cooperation and interaction between librarians and educational planners to meet this requirement.

The explosive growth of the web-based resources coupled with high-rate of change has made an up-to-date index needed for search (engines) a challenge. Crawlers are no longer capable of keeping up pace with the rapid growth of web using traditional approaches. The present paper offers an alternative method called distributed crawling using mobile agents. The aim is to offer a scalable crawling methodology that is less network intensive, would keep pace with changes in resource profiles, employs time perception and could be easily upgraded.
