    Abstract
    A known-item search for abstracts to previously retrieved references revealed that 2 documents from the same annual volume had been indexed twice. Working from the premise that the whole volume may have been double-indexed, a search strategy was devised that limited the journal code to the year in question. 57 references were retrieved, comprising 28 pairs of duplicates plus a citation for the whole volume. Author, title, source and descriptors were requested off-line and the citations were paired with their duplicates. The 4 categories of descriptors-major descriptors, minor descriptors, subheadings and check-tags-were compared for depth and consistency of indexing and lessons that might be learnt from the study are discussed.

    Abstract
    Presents a structured abstract of the actual article. Outlines the debate on the value of structured abstracts and describes a research project into their use, which investigated records of cardiovascular disease downloaded from MEDLINE and tested against clinical questions derived from a survey of CD-ROM use in 3 health science libraries. It was found that structured abstracts improve precision at the expense of recall and place heavier demands on the skills of selecting fields to search within the abstract. Indicates directions for further research
