- Abstract
- Reports results of a comparative study of 3 classification schemes: LCC, DDC and NLM Classification to determine their effectiveness in classifying materials on health insurance. Examined 2 hypotheses: that there would be no differences in the scatter of the 3 classification schemes; and that there would be overlap between all 3 schemes but no difference in the classes into which the subject was placed. There was subject scatter in all 3 classification schemes and litlle overlap between the 3 systems
