Expression-level bibliographic entity records: A trial on creation from pre-existing MARC records

This paper reports on a study to investigate the feasibility of creating bibliographic records in accordance with a model giving primacy to expression-level entity, through attempts on converting existing MARC records. First, methods of creating records were examined in terms of the structure of records. A method that explicitly shows the structure of the model on which records were based was then selected. Second, a trial was conducted to convert USMARC bibliographic records into those structured according to the method selected, by developing programs to facilitate conversion. Third, a prototype system to use the structured records was developed in order to demonstrate the usefulness of such records.
