The California State University at Northridge has launched a $16 million project to expand its existing library. One of the prominent features of the addition will be an automated storage and retrieval system named Leviathan II. The system will store some 950,000 volumes in bins along six long aisles. When a patron requests a book at a computer terminal, a mechanical retrieval device will bring the appropriate bin to a workstation at a public service desk where staff will sign the wanted material out to the patron. The Library plans to store up to half of its collection in Leviathan II. If successful, the system may be replicated at other California State campuses. Plans are to use the Geac system already installed in the Library as the patron access device. While the mechanical portions of the system are similar to those installed in Europe, the interface with a local library system's patron access catalog is believed to be unique.
