This study aimed to determine the status of Persian professional web social networks' features and provide a suitable solution for optimization of these networks in Iran. The research methods were library research and evaluative method, and study population consisted of 10 Persian professional web social networks. In this study, for data collection, a check list of social networks important tools and features was used. According to the results, "Cloob", "IR Experts" and "Doreh" were the most compatible networks with the criteria of social networks. Finally, some solutions were presented for optimization of capabilities of Persian professional web social networks.

Aiming to study the freshness of Persian information, this study attempted to explore the indexing speed of Persian newspapers in Google, Yahoo and Bing. The present study was conducted using a webometric method. The population of the study consisted of all online newspapers published in Persian. The study sample was identified using a targeted method. It included those Persian newspapers listed on the MagIran database with their electronic versions regularly published on their respective websites. The results revealed that Google outperforms the two other search engines in terms of timely indexing of the Persian newspapers. Furthermore, it generally enjoys a more consistent and stable indexing model. Yahoo and Bing are not only slower in indexing the newspapers, but also experience a comparably lower consistency level in their indexing models. Yahoo and Bing show to be comparable in their indexing speeds. In this study, the indexing status of Persian newspapers on different internet search engines was investigated for the first time. Results showed that those accessing these newspapers using internet search engines will have a higher chance of accessing their most updated versions using Google. © 2015 Journal of Information processing and Management.

Cloud Computing is dominant mode of current and future of information and communication technologies. It is not beyond the realm of possibility that it would foment upheaval within libraries and information centers service-wise. The wide-reaching extent of these changes would envisage a new feature to libraries both in organization and service delivery. The present study, employing a descriptive analysis method, examines the concepts of cloud computing while laying the foundations for a cloud-based library as its corollary. While presented as a conceptual construct, the paper posits that the model can solve some of the issues such as digital right managements as well as copyright. Several models are offered and discussed with respect to applicability, missions, client group, financing as well as service blendals.

There are different theories on information as Shannon's Information or Communication Theory, Semantic Theory of Information, Cybernetics Theory, Quantum Theory of Information and Quantum Information Theory, each one viewing information from a different point. In this paper researchers used the foundamental concepts of quantum physics such as Wave/Particle duality, Complementarity, Uncertainty principle, Schrödinger's cat &so on to explain the nature of information and its role in information environments & flows. These concepts were introduced sequentially and Quantum Theory of Information was interpreted eventually.
