The best-integrated library software and LMS software have started using the Internet of Things (IoT) to transfer data without human intervention. Libraries use IoT to control inventory, prevent theft, and identify users. It also helps in improving the quality and speed of circulation desk activities. Moreover, IoT expedites reservation of books, fire detection in the library and its prevention, and streamline eLibrary services. Big Data and Data Visualization is the method of displaying a large volume of data through charts, graphs, maps, and other visual forms. This makes the info more natural for the human mind to grasp and makes it easier to spot trends, patterns, and outliers within large data sets. This technology is helping digital libraries become more globalized while accessing a vast amount of data. It makes the libraries more easily accessible to readers who can find a plethora of information at their fingertips. Artificial intelligence (AI) uses the power of a robot or a computer that tries to do tasks that humans usually do. The most common application of AI in a library is the chatbots that receive directional questions from users and resolve them. They can alert the user about their book submission due date, direct a user to the relevant library segment, and automatically schedule appointments. The three main objectives of a library are to promote literacy, disseminate useful daily information to the people and encourage lifelong learning through its reading materials and resources. This publication will be a highly useful reference book to the library professionals.
