事实告诉我们:纯分面的分类法和纯体系的分类法都难以承担对文献进行分类排架和组织分类目录的双重职能,因此,文献分类法当前的发展趋势是:组配分类法向体系分类法靠拢,体系分类法向组配分类法靠拢。那么,怎样实现体系分类法向体系组配分类系统过渡而组配分类法向组配体系分类系统过渡呢? The facts tell us that both the pure surface classification method and the pure system classification method can hardly undertake the dual functions of classifying documents and organizing the catalogs. Therefore, the current development trend of document classification methods is as follows: Taxonomy approach, system classification method to move closer to the classification. So, how to achieve the transition of the system classification system to the classification system and the classification system to the classification system?
