    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.
