Online libraries are digital collections of books, articles, and other resources that can be accessed via the internet. They allow users to read and borrow materials from the comfort of their homes, making it easier for people to find information and enjoy literature. Many online libraries offer a wide range of genres, including fiction, non-fiction, and academic texts, catering to diverse interests and needs. These libraries often require a membership or a library card, which can be obtained from local public libraries. Some popular online libraries include Project Gutenberg, which offers free eBooks, and OverDrive, which allows users to borrow eBooks and audiobooks from their local library.
