    Abstract
    Reviews literature on the main expert systems used in descriptive cataloguing. Discusses the features and problems of the three types of systems which have developed: advisory systems, systems to create bibliographic records and systems to carry out original cataloguing. The quantity and complexity of the rules of a cataloguing code make it difficult for them to be incorporated into the knowledge base of an expert system

    Abstract
    A review of the literature. Authority control is intended to improve precision and recall but high failure rates detected during online catalogue searches by end users has given rise to debate about whether the time and effort involved in this approach is justified. Suggested solutions include using a combination of indexing techniques, increasing access points, greater standardisation of formats and more powerful software. Cooperative programmes at national and international levels can reduce costs. In Latin America some libraries use US / European formats, while others have developed their own local or regional systems; the whole situation needs to be reviewed to resolve the anomalies
