    Abstract
    Reference librarians, who are thoroughly familiar with the purpose, scope and arrangement of abstract periodicals, are uniquely qualified for the task of writing abstracts. The procedures described here offer a relatively simple way for them to write acceptable abstracts from the outset. Although research is being conducted in the area of machine generated abstracts, there wll continue to be a role for human abstractors.

    Abstract
    A survey of abstracting policies by producers of bibliographical databases examined abstracting guidelines which aim to enhance free- text retrieval. Of the 123 database policies examined, fifty-seven (46 per cent) included such instructions. Editors consider contents of abstracts and their language as a primary factor in retrieval enhancement. Most recommend that once abstractors decide which concepts to include in abstracts and in which form to represent them, these terms should be co-ordinated with index terms assigned from a controlled vocabulary. Guidelines about the type of abstracts, i.e., informative or indicative, and about their length are not affected by the capability of free-text retrieval
