Janus is a self-funded project, established in October 2002 to provide a single point of networked access to catalogues of archives and manuscript collections held throughout Cambridge. The number and range of participating repositories - both University and non-University - continues to widen, promising in due course the near comprehensive coverage of archives in the city and surrounding area.<br />
The site was named ‘Janus’ after the god of gates and doors in Roman mythology. The god Janus has a distinctive appearance in art and is often depicted with two faces. Some sources claim that the reason Janus was represented in this way was a reflection of the concept that doors and gates look in two directions. In this way, one of the god's faces could look forward, while the other looked backward. By embracing new technology, Janus looks forwards, while the content of the site looks back. The site's logo is based on the above Roman coin showing the god Janus.
