In this study highly cited publications are determined using citations from the Science Citation Index (SCI) database and source documents from a non-SCI database. Instead of the journal-impact factor, which in this case is questionable as a reference standard, the average citation rate of a subfield was used for the analysis of European physics papers published in the period 1980-87 and covered by the Physics Briefs database. The methodology is followed by a detailed analysis of the results obtained. The discussion includes an analysis of the number, and the absolute and relative share, of highly cited papers by countries. The added value of indicators based on highly cited papers to other indicators such as the citation mean is shown. The paper concludes with an investigation of the role of international collaboration among highly cited papers.
