An Online Library is a digital platform that provides access to a vast collection of books, articles, and other educational resources over the internet. Users can browse, search, and read materials from the comfort of their homes, making it convenient for students, researchers, and avid readers. Many online libraries offer features like e-books, audiobooks, and academic journals, catering to diverse interests and needs. These libraries often require a membership or subscription, while some resources are available for free. Popular examples of online libraries include Project Gutenberg, which offers free e-books, and Google Books, which provides previews and access to a wide range of publications.
