Only a small proportion of the more than 1,100 entries have been retained from the earlier editions and supplements, 1955 to 1983; more publications reflecting social and economic changes in South Africa have been included; and the annotations are more extensive. The main focus is on references such as dictionaries, yearbooks, and encyclopedias, but handbooks, manuals, and histories are cited if no conventional references exist on the subject. The selection is not limited to books published in South Africa. The arrangement is by broad subject headings following the Dewey Decimal system. The annotations are primarily descriptive, but evaluations creep in now and again. Distributed by Books International. Annotation copyrighted by Book News, Inc., Portland, OR
