    Abstract
    In online retrieval search results do not always match the intent in spite of using correct keywords (descriptors). One of the causes of this problem is found in the hierarchical structures of the thesaurus, which often contains relations between broader and narrower concepts, the opposite of which is not necessarily true. Some examples are described from 2 thesauri, MeSH and JICST. In these cases searchers need to make an effort to increase precision

    Abstract
    The Nippon Decimal Classification (NDC) system, extensively used in Japanese libraries, was devised in 1929. It is difficult to use NDC to classify world literature, such as fiction in English by non American, non British writers. This is not necessarily straightforward in other classification schemes but a survey of 40 Japanese university libraries, of which 24 responded, showed remarkable inconsistencies in the treatment of 22 world literature authors. NDC clearly needs updating to deal with this problem
