A random sample of fifty nursing articles indexed in both MEDLINE and CINAHL (NURSING & ALLIED HEALTH) during 1986 was used for comparing indexing practices. Indexing was analyzed by counting the number of major descriptors, the number of major and minor descriptors, the number of indexing access points, the number of common indexing access points, and the number and type of unique indexing access points. The study results indicate: there are few differences in the number of major descriptors used, MEDLINE uses almost twice as many descriptors, MEDLINE has almost twice as many indexing access points, and MEDLINE and CINAHL provide few common access points.
选取了1986年在MEDLINE和CINAHL（护理与联合健康）中均被索引的50篇护理文章的随机样本，用于比较索引编制方法。通过统计主要描述词数量、主要和次要描述词数量、索引检索点数量、常见索引检索点数量以及独特索引检索点的数量和类型来分析索引编制。研究结果表明：在使用的主要描述词数量上差异不大，MEDLINE使用的描述词几乎是其两倍，MEDLINE的索引检索点几乎是其两倍，并且MEDLINE和CINAHL提供的共同检索点很少。
