    Abstract
    Paper presented at a symposium on 'Implementing the Art and Architecture Thesaurus (AAT): Controlled Vocabulary in the Extended MARC Format', held at the 1989 Annual Conference of the Art Libraries Society of North America. Examines the structure of subject headings in the light of machine manipulation. Draws attention to the fact that as on-line cataloguing systems become more sophisticated, and the results of search experiments demonstrate the inadequacy of present modes of subject access to bibliographic and image data, the structure of subject headings become more critical, and changes will continue to occur.

    Abstract
    The Art and Architecture Thesaurus (AAT) was designed as a comprehensive vocabulary in its domain. Its faceted, hierarchically arranged structure allows for powerful indexing and retrieval capabilities, while its planned network of related term relationships makes it especially amenable to natural language processing. To gauge the AAT's effectiveness as a search tool against natural language queries, an experiment was carried out on DIALOG. There are 3 art data bases on DIALOG and there are also a number of other data bases that contain art related material. The experiment used queries culled from reference librarians at art and architecture libraries.
