Types of Libraries: Academic, Public, Special and National Libraries.
Libraries are essential institutions for education, research, information access, community development and preservation of knowledge. Although all libraries aim to provide information resources and services to users, their objectives, collections, users and functions differ according to their purpose.
The four major types of libraries commonly discussed in Library and Information Science (LIS) are Academic Libraries, Public Libraries, Special Libraries and National Libraries. Understanding the characteristics and functions of these four types is important for LIS students, library professionals and candidates preparing for competitive examinations such as UGC NET, CUET, university recruitment examinations and other Library Science exams.
This article provides a comprehensive overview of the types of libraries, their characteristics, major functions, users, collections, services and important differences.
