Condensed in one affordable volume, Abridged Edition 13 is designed to meet the needs of libraries with fewer than 20,000 titles. If your library does not need to classify in great detail, it's the perfect choice. Major revisions of 350-354 Public administration, 370 Education, 570 Life sciences, 580 Plants, and 590 Animals. New table numbers for countries of the former Soviet Union. Updated terminology and new topics including virtual reality, Internet, rap music, and in-line skating. Over 40 pages of additional index terms. Numbers compatible with DDC 21, so libraries can expand from the abridged to the full edition.
