ABSTRACT

Another method is to include instructions within the schedules themselves for dividing one classification number in the same manner as another. All plants, for instance, may suffer from ‘injuries’, ‘diseases’ and ‘pests’. Instead of enumerating each of these concepts under every individual plant, they can be listed once and instructions given for the division of each plant in the same way. PRACTICAL EXAMPLES OF SYNTHESIS IN A BASICALLY ENUMERATIVE SCHEME

Example 7.1 Bibliographic Classification (Bliss, 1940-53) The 1940-53 edition of this general classification scheme for library materials by H.E. Bliss is essentially enumerative but a certain amount of synthesis is provided for by ‘systematic schedules’, some of which may be applied throughout the scheme but others are applicable only in specific classes. Below are shown extracts from two schedules of the former variety:

SCHEDULE 1 NUMERAL DIVISIONS OF ANY CLASS OR SECTION
