- Abstract
- Major changes in the DDC-20 are discussed, with particular reference to: the complete revision of music (780); the expanded possibilities in computer science and data processing (001-006); revision of geographical areas for some parts of the world; changes and revision in religion, media, elelctronics. Also stresses important relocations of subject, such as: clinical psychology and home economics. Important expansions have also taken place in the various tables: some of 02 in table 1; the expansion of table 3; the expansion of African topics in both tables 5 and 6. The addition of numerous notes and recommendations is useful. The new index is criticized for the fact that instructions for use are placed in vol.1 rather than in the index itself. The publication of the manual together with the schedules is welcomed, but the separation between the instructions in vol.1 and in the manual of vol.4 is confusing, since most of these issues belong together. On the whole, the new edition reflects adequately the 'literary warrant of the last decade'
