Purpose: Determining the use of Internet of Things (IoT) in selected librariesMethod: This survey used a researcher-made checklist. ؟ ؟experts confirmed the validity of the tool. Websites of twenty libraries as well as the literature about the use of the IoT by them were examined. Also we contacted with relevant people in the target libraries to receive additional data. Types of libraries, services provided by IoT technologies and tools were investigated.Findings: The libraries benefited from 1) Radio wave identification technology (RFID); 2) Bluebeam technology; 3) Smart camera 4) Smart public areas project; 5) Hui Wen library information service system; 6) Montreal; 7) Book robot; 8) Smart robot; 9) Car to Car communication; 10) Capira mobile application is used to provide services. Bluebeam technology provided users with widest range of all the 10 services. Hui Wen's library information service system by benfiting from eight applications came top in using IoT.Conclusion: The very fact that libraries studied continue to use IoT, may suggest that Iranian libraries should consider employing this emerging technology

Nowadays, with the increasing population of the world and the need for food on the one hand and the scarcity of water, energy and arable land on the other hand, traditional agriculture is no longer responsive to the food demand of the world population, so smart farming has become more and more popular. The IoT is a new technology that is capable of providing many solutions for modernizing agriculture. IoT provides reliable information on the seed to be sown, the seed rate, the best time to plant and harvest, as well as the prediction of the amount of crop to be harvested. In this article, by studying research and research through library data collection and the study of scientific resources in the field of IoT, as well as the infrastructure required for deployment, we discuss the potentials and capabilities of this technology In the field of agriculture. The present study reviews the benefits of using IoT in smart agriculture such as increasing crop yields due to proper planning of seed planting time, crop harvesting, water use optimization. Planning to apply appropriate irrigation methods according to the amount of water required for each plant and each climatic zone, identifying pests and plant diseases at the real time, and alerting the farmer to the necessary decisions and actions to be taken. Pest utilization of information obtained from sensors established in the field is another benefit that has been addressed in this study.
