- Subject-oriented bibliographic online searching relies in most cases on the results of verbal subject analysis (descriptors, subject headings, keywords, text of abstract). However, many bibliographic databases are also searchable by classification codes. This paper deals with the latter form of subject access, mainly pointing out the role of classification codes (class codes) as a useful enrichment to verbal online searching. Part 1 discusses the following questions: To what extent are classification schemes as a means of subject access to be found in bibliographic databases? What is the nature of these systems and their notation? Part 2 shows several advantageous applications of using classification codes in bibliographic online searching. Part 3 deals with modifications and changes of classification systems, which constitute the main problem when using them in online searching. Thus, the searcher not only has to be informed how to apply classification for improving search strategies, but also how to overcome such difficulties.
