A library is a physical or virtual collection of books, media, and digital resources accessible to its members for learning, research, and recreation. Libraries provide a quiet environment for reading and studying, offering access to a wide range of materials including books, magazines, newspapers, films, and music. They are community hubs that promote lifelong learning, preserve cultural heritage, and provide essential resources like internet access and homework help, often supported by trained librarians who assist users in finding and using information.
