The Curator is a Hologram designed by the makers of the EMH to work as a liaison between the Science Computer Core, specifically the Library Database, and the Science Officers. As such, it is equipped with an etiquette program and search pattern enhancers, using the Computer Core in the way of an actual Library Custodian. His appearance is the same as the EMH Mark 1, however the medical treatments have been replaced by an extensive knowledge of chemical components and science equipment.
The Curator (Class type: LAH) was installed on the USS Montreal in 2285, at the request of the Science division, and was the first hologram of its type to be used. In 2290, the LAH was extended to several other places, however the original still resides on the USS Montreal.
