Abstract：Transformation of educational roles of library-supported mobile learninga literature review from 2009 to 2018 Purpose This study aims to explore the transformation of the roles of librariesapplication trends and potential research issues of library-supported mobile learningDesignmethodologyapproach The publications in the Scopus database from 2009 to 2018 are reviewed and analyzed from various aspectssuch as the roles of libraries in mobile learningtypes of librariesresearch foci and sensing or location-based technologiesFindings The role of libraries as learning material providers is examined the most in library-supported mobile learning studiesfollowed by the role as inquiry context providers and as knowledge-sharing platformsIn terms of the role as learning material providersacademic libraries were investigated the most and radio frequency identificationRFIDwas mainly adoptedIn terms of the role as inquiry context providersspecial libraries were explored the mostadopted sensing technologies were more diverseegQR codeaugmented realityRFID and Global Positioning SystemOnly special libraries played a role as knowledge-sharing platformsadopting augmented realityMost research on library-supported mobile learning mainly focused on investigating the affective domain during mobile learningPractical implications Five potential applications of educational roles in library-supported mobile learning are suggested based on the findings of the present studyOriginalityvalue The current study provides insights relevant to the educational roles of library-supported mobile learningThe findings and suggestions can serve as references for researchers and school teachers conducting library-supported mobile learningLibrary AutomationThrough RFID technologyit is easier to track and manage items in the libraryRetrieval and IndexingRFID and other sensing technologies can help users find and query the librarys information and resources quicklyIn this studytechnologies mainly adopted in library-supported action studiessuch as RFID recognitionRFIDQR codeamplification realityand global positioning systemGlobal Positioning SystemAmong themRFID is an IoT technology that is usually used for object recognition and tracking
