Abstract：Intelligent librariesa review on expert systemsartificial intelligenceand robot PurposeThis paper reviews literature on the application of intelligent systems in the libraries with a special issue on the ESAI and RobotAlsoit introduces the potential of libraries to use intelligent systemsespecially ESAI and robotsDesignmethodologyapproachDescriptive and content review methods are appliedand the researchers critically reviewed the articles related to library ESs and robots from Web of Science as a general database and Emerald as a specific database in library and information science from 20072017Four scopes considered to classify the articles as technologyserviceuser and resourceIt is found that published researches on the intelligent systems have contributed to many librarian purposes like library technical services like the organization of information resourcesstorage and retrieval of information resourceslibrary public services as reference servicesinformation desk and other purposesFindingsA review of the previous studies shows that ESs are a useable intelligent system in library and information science that mimic librarian experts behaviors to support decision making and managementAlsoit is shown that the current information systems have a high potential to be improved by integration with AI technologiesIn this researcheslibrarian robots mostly designed for detection and replacing books on the shelfImproving the technology of grippinglocalizing and human-robot interaction are the main concern in recent librarian robot researchOur conclusion is that we need to develop research in the area of smart resourcesOriginalityvalueThis study has a new approach to the literature review in this areaWe compared the published papers in the field of ESAI and robot and library from two databasesgeneral and specific Consulting ServiceIt supports decision-making and management through the expert behavior of the library through the expert systemLibrary AutomationBooks on the bookshelf through robot detection and replacement of booksRetrieval and IndexingThe integration of AI can improve the storage and retrieval efficiency of information resourcesThis paper mainly discusses the intelligent system applications in the libraryespecially the expert systemESand robotsThe expert system of the expert system imitates the expert behavior of the librarian in the book information science to support decision-making and managementIn additionthe existing information system has great potential for further improvement through integration with AI technologyThe library robot is mainly designed to detect and replace books on bookshelves
