A virtual library is a digital space that keeps and organizes virtual books and their associated documents. These spaces can include computers, mobile devices and the Internet. Some virtual libraries can be accessed for free, and others require subscriptions. An advantage of using a virtual library is that it is able to store many books in a small amount of space. Physical books can take up a lot
of space. By using a digital library, readers can access their entire personal libraries in one location, on either a computer or a mobile device. The need for physical books diminishes by using a virtual library, so digital libraries also have the benefit of helping to conserve paper resources. The term "virtual library" also can be used to refer to a collection of books that are readily available to be read on the Internet. These books often can be read for free and are available under public domain. Any users who find a book under one of these circumstances can read it and use it within the terms set forth by the organization providing the books. They must also follow any laws connected to reading the book.
