- 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

- Abstract
- Structured abstracts have now become widespread in medical research journals. Considers whether or not such structured abstracts can be used effectively in social science journals. Reviews a a selection of studies to see if structured abstracts written for social science journals are more informative, easier to read and easier to search than their traditional equivalents. Results suggest that structured abstracts are appropriate for social science journals. Editors of social science journals should consider adopting structured abstracts

- Abstract
- Reports results of a study to consider whether or not structured abstracts can be used efectively in non medical science periodicals. Reviews a selection of studies on structured abstracts from the medical and psychological literature, presents examples of structured abstracts published in non medical science periodicals and considers how original abstracts might be written in a structured form for these periodicals. Concludes that, in light of these example studies, editors of these periodicals should consider the value of adopting structured abstracts

- Abstract
- Purpose - The literature on abstracts recommends the revision of author supplied abstracts before their inclusion in database collections. However, little guidance is given on how to carry out such revision, and few studies exist on this topic. The purpose of this research paper is to first survey 187 bibliographic databases to ascertain how many did revise abstracts, and then study the practical amendments made by one of these, i.e. LISA (Library and Information Science Abstracts). Design/methodology/approach - Database policies were established by e-mail or through alternative sources, with 136 databases out of 187 exhaustively documented. Differences between 100 author-supplied abstracts and the corresponding 100 LISA amended abstracts were classified into sentence-level and beyond sentence-level categories, and then as additions, deletions and rephrasing of text. Findings - Revision of author abstracts was carried out by 66 databases, but in just 32 cases did it imply more than spelling, shortening of length and formula representation. In LISA, amendments were often non-systematic and inconsistent, but still pointed to significant aspects which were discussed. Originality/value - Amendments made by LISA editors are important in multi- and inter-disciplinary research, since they tend to clarify certain aspects such as terminology, and suggest that abstracts should not always be considered as substitutes for the original document. From this point-of-view, the revision of abstracts can be considered as an important factor in enhancing a database's quality.
