Abstract：Libraries in Internet of ThingsIoTera PurposeInternet of ThingsIoThas been widely adopted in the commercial sectorAlthough IoT enables traditional libraries to convert into digital onesthe implementation of the IoT in libraries is slowThe purpose of this paper is to report on the current state of research on applications of IoT in librariesdescribe challenges that IoT applications face in libraries and discus directions of adopting IoT in libraries in the futureDesignmethodologyapproachTo conduct this researchthe literature of IoT and its application in libraries were reviewed by examining existing literature in Institute of Electrical and Electronics EngineersIEEEXploreFindingsThe literature review finds that radio-frequency identification has been adopted by digital librariesThe slow implementation of IoT is caused by security and privacy issueslack of standards and the lack of financialtechnological and organizational resourcesThis study provides a prospective for the application of IoT in librariesthe technologies of IoT have the potential in betterment of library servicesResearch limitationsimplicationsThe limitation of this study is that only IEEE Xplore is includedOther database should be explored in future researchOriginalityvalueThe application of IoT in libraries is an emerging issuea systematic and extensive review of recent research on applications of IoT in libraries is unavailableThis paper presents an overview of IoT in librariesfindings and potential research opportunitiesLibrary AutomationRFID technology is used in the library system that is used in automationmaking it more convenient to track and manage itemsConsulting ServiceWith the development of IoT technologylibraries may provide more IoT-based consulting services to help readers understand and use these new technologiesInstificational CollectionThrough IoT technologylibraries can manage and monitor their collection items more effectivelyThis article explores the application status of the Internet of ThingsIoTin the librarychallengesand future development directionIt is specifically mentioned in the article that although IoT technology has been widely used in the business fieldthe implementation of the library is still slowThrough the literature reviewthe author found that RFID technology has been adopted by several librariesand the slow implementation of IoT technology in the library is mainly due to security and privacy issueslack of standardsand lack of financialtechnical and organizational resources
