School libraries can exist in two spaces, a physical space or a virtual space. The author argues that students need a virtual library as well as a physical library because of the different learning opportunities that can be supported by virtual libraries. If a virtual library is carefully planned and designed, it can provide a rich learning environment. Although some authors may distinguish between various terms used to describe virtual libraries: digital libraries, electronic libraries, e-libraries, and the broader term virtual library, in this article, the term virtual library is used to describe any managed collection of information sources in an electronic format. Therefore, virtual libraries could include digital collections of pictures, maps, Web sites, or library records.
