A virtual library is an online collection of digital resources, including e-books, articles, and multimedia content. These libraries allow users to access a wide range of information from anywhere with an internet connection. They often provide search tools and organizational features to help users find specific materials quickly. Many virtual libraries are affiliated with educational institutions, such as universities or public libraries, and may require a membership or student login for full access. Examples of virtual libraries include Project Gutenberg, which offers free e-books, and Google Books, which provides previews and access to a vast array of published works.
