title: Citation patterns in tropical medicine journals.
abstract: Selections of most important journals in the field of tropical medicine have previously been identified with the help of resources such as bibliographical and citation databases. This article uses ISI's Journal Citation Reports (JSR) for 2002 to analyse the citation characteristics of the Tropical Medicine category. According to these data, this small but diverse group of 12 journals bestows some 40% more citations than it receives. Its six typical core journals tend to cite one another heavily, but they also refer a lot to multidisciplinary science and general medicine journals, and to infectious diseases and parasitology journals. Looking at the sources from which JCR's tropical medicine journals derive their citations, it is clear that in this reverse direction, the specialty's literature is still more concentrated. Apart from the typical core, this JCR category also contains a number of journals with more idiosyncratic citing patterns, focused on specialties such as paediatrics, a single disease (leprosy) and a representative of Latin American and Francophone biomedical science each. Implications of concentrated citedness and language biases are discussed briefly. This paper features a selection of bibliometric parameters relating to the tropical medicine journals and lists of the 80 journals most citing and cited by them.
