The Paintings Specialty Group (PSG) of the American Institute for Conservation of Historic and Artistic Works (AIC) welcomes you to the Paintings Conservation Wiki page. The Paintings Specialty Group was formed in 1980 and is composed of members from the United States and the international community and includes conservation professionals from historic sites, museums, private practice, and regional centers. The purpose of the PSG is to improve knowledge of all subjects relating to the conservation of paintings, to promote proficiency and skill in the practice of paintings conservation, and to disseminate related technical and professional information.
The wiki was originally structured according to the outline of existing and proposed chapters of the Painting Conservation Catalog (1998-present). The wiki is a growing, evolving source of information and, as such, the content, including sections of the extant Painting Conservation Catalog chapters, will continue to evolve on the wiki. The published chapters in their unaltered form are available for digital download through the AIC Online Store.
