The purpose of this study was to determine the amount of correlation between National Library of Medicine classification numbers and MeSH headings in a body of cataloging which had already been done and then to find out which of two alternative methods of utilizing the correlation would be best.There was a correlation of 44.5% between classification numbers and subject headings in the data base studied, cataloging data covering 8,137 books. The results indicate that a subject heading index showing classification numbers would be the preferred method of utilization, because it would be more accurate than the alternative considered, an arrangement by classification numbers which would be consulted to obtain subject headings.
本研究的目的是确定在已完成编目的一批文献中，美国国立医学图书馆分类号与医学主题词之间的相关程度，然后找出利用这种相关性的两种替代方法中哪种最佳。在所研究的数据库（涵盖8137本书的编目数据）中，分类号与主题词之间的相关性为44.5%。结果表明，显示分类号的主题词索引是首选的利用方法，因为它比另一种考虑的方法更准确，后者是按分类号排列以便查找主题词。
