Abstract：Internet of ThingsIOTand library services Purpose The purpose of this study is to analyze the existing literature on the application of the Internet of ThingsIoTand to give an overview of how libraries are adopting this emerging technology to make users feel more engaging with the library resources and service provisionDesignmethodologyapproach The basic architecture of IoT with its functionality has been enumerated and its different layers have been depictedFindings A conceptual library IoT modelworking on Message Queuing Telemetry Transport protocolbased on the fog-cloud computing layer of architecture has been proposedThis study also highlights the sensor-based current library servicesOriginalityvalue This study focuses on the existing practices of adoption of library IoT and discusses the possibilities of its future expansion in different areasLibrary AutomationThrough IoT technologyresources and facilities can be automatically trackedRetrieval and IndexingDevice can collect data through IoT protocolssuch as MQTTwhich may help data retrieval and indexThis part mainly discusses the concept and application of Library Internet of ThingsLioTIoT allows various objects in the library to communicate with each other without manual interventionThis allows users to easily track resources and facilitiesIn additionLioT also involves communication with specific protocolssuch as MQTTand how to store and process data securely
