    Abstract
    The following investigation is a comparison between the Art and Architecture Thesaurus (AAT) and the LC Thesaurus for Graphic Materials (LCTGM), two popular sources for providing subject access to visual archives. The analysis begins with a discussion on the nature of visual archives and the employment of archival control theory to graphic materials. The major difference observed is that the AAT is a faceted structure geared towards a specialized audience of art and architecture researchers, while LCTGM is similar to LCSH in structure and aims to service the wide-spread archival community. The conclusion recognizes the need to understand the differences between subject thesauri and subject heading lists, and the pressing need to investigate and understand intellectual control of visual archives in today's automated environment.

    Abstract
    Assesses the current state of reference structures in OPACs in a framework defined by stagnation, progress, and future challenges. 'Stagnation' referes to the limited and inconsistent reference structure access provided in current OPACs. 'Progress' refers to improved OPAC reference structure access and reference structure possibilities that extend beyond those commonly represented in existing subject autgority control tools. The progress discussion is supported by a look at professional committee work, data modelling ideas, ontological theory, and one area of linguistic research. The discussion ends with a list of 6 areas needing attention if reference structure access is to be improved in the future OPAC environment
