对全国5个较有代表性的书目数据库进行比较研究,发现其中的书目数据存在较大的差异,原因大致有各馆对中文MARC字段的理解不同,著录的繁简尺度不同,书目数据的交流和编目人页彼此学习探讨的机会都太少,等等。就此,提出MARC著录的几个原则。 A comparative study of five representative national bibliographic databases reveals that there is a large discrepancy in the bibliographic data among them. The reason is roughly that different pavilions have different interpretations of the Chinese MARC field, different scales of bibliographical transcription, and exchange of bibliographic data And cataloger pages to learn from each other too little chance of discussion, and so on. In this regard, put forward several principles of MARC bibliography.
