Abstract：Artificial Intelligence and its applications in Libraries In this paper an attempt has been made to trace the different applications of Artificial Intelligence to the librariesThe various concepts such as expert systemnatural language processingpattern recognition and robotics and their application to the libraries have enumeratedThe advantages and disadvantages of Artificial Intelligence have also been discussed Library AutomationThrough roboticsit can be classified and sorted out of automated booksConsulting ServiceThe expert system may be used to provide consultation or recommendation servicessuch as books or information recommendationsRetrieval and IndexingThrough NLP and mode recognitionmore efficient and accurate data retrieval can be achievedExpert SystemsThe article refers to the expert system that simulates the decision-making process of human experts and provides professional knowledge and suggestions in specific fieldsNLPNatural Language ProcessingThe article refers to natural language processingwhich is a technology that allows machine understandinganalysisand response to human languageRoboticsThe article also talks about roboticswhich is part of automation technology to simulate or enhance certain human movements or functionsPattern recognitionThis technology enables the machine to recognize and classify the data mode
