The Australian Archives A.C.T. Conservation Laboratory performs various tasks relating to the preservation program. The two streams of work - Treatment of Materials and Laboratory Services are considered to be of equal importance. The first deals with the actual treatment of items in the collection while the latter concerns preventive conservation, During the period of my internship I have carried out most of the Laboratory Services which I will discuss in this dissertation with the exception of Disaster Planning. I was also involved in the treatment of various objects from the Australian Archives collection as well as from other government agencies, completed with written and photographic documentation. One of the projects, taking several months of treatment, was a series of old letter books containing letters from the Administrator in Sydney to the Chief Magistrate of Norfolk Island. This project, along with the conservation of some other government records, demonstrates the difference between archival conservation and conservation of other art and cultural objects. Attendances at technical seminars and conferences are also discussed.
