Secondary results, manual data

Much of the work in this area has arisen from the conversion to machine processing of formerly manual operations by the publishers of secondary literature. Taking Chemical Abstracts Service as a prime example, they began to computerise their operations in the early 1950 s, primarily to increase their efficiency in coping with the ever-increasing flood of primary literature. As a result, their secondary data bases have b un to appear in computer-readable form, in essentially natural language, beginning with Chemical Titles in 1962. These data bases can then form the basis of computerised retrieval services such as those offered by UKCIS 42).
