The homepage of London's Science Museum hosts numerous online features and exhibitions that will appeal to a wide audience. Continually updated, the site features both companion pieces to current exhibits in the physical museum and Web-only items. Attractive, easy to navigate, and quick-loading, current offerings include Fusion, The Art of Invention, Materials, and Dolly the Sheep, among others. Numerous exhibitions offer animated or other video content in QuickTime format, and at least one section of the site (the Wellcome Wing) requires the Cortona VRML plug-in (Windows systems only). For researchers, information on various Museum resources, including an online catalog of its library, is provided. Information for prospective visitors is also posted.
