In 1987, an analysis of the CHI/NSFScience Literature Indicators Data-Base by the author and his colleagues suggested that the UK's percentage share of the world publication and citation totals had continued to fall over 1981–84, although at a slower rate than previously. That finding has recently been challenged byBraun, Glänzel andSchubert who, by combining 28 publication-based indicators, concluded that there was no statistically significant evidence for such a decline. This paper examines the reasons for the discrepancy. It is argued that the methodology ofBraun et al. is seriously flawed, as well as being inconsistent with work that they have published elsewhere. By adopting a more consistent and realistic set of indicators and applying them to the data ofBraun et al., one arrives at results entirely consistent with those derived from the CHI/NSF data-base.
