Electronic cataloguing systems are used by libraries to provide search mechanisms for finding books in their collections. These systems provide limited, if any, tools for browsing content electronically in a manner similar to browsing books on physical library shelves. Furthermore, library patrons often struggle to physically locate and retrieve books, even after they have found what they are looking for using library catalogue systems. A number of prototype technologies have been developed in recent years to assist library users with the task of locating books. These systems are, however, rather limited in their functionality, and generally do not provide tools for remote browsing of library shelves. In this paper we introduce Metis, a system designed to allow virtual viewing of collections, and to assist with physical retrieval of books using a range of desktop and mobile computing devices.
