This document sets forth the principles that guide conservation professionals and others who are involved in the care of cultural property. This core document grew out the Murray Pease Report (on standards and priactice), published in 1963, and later Code of Ethics for Art Conservators (1967). Combined and revised in 1979 into two parts, the document was then amended in 1985 to reflect additions to the AIC Bylaws on reporting, investigating, reviewing, and appealing violations. From 1985-93, they were simplified, subjected to comparative analysis, organized topically, and related to other codes in conservation and other professions. They were adopted by AIC's voting membership in 1994.
