||Research evaluation is used to identify ?success? and relate this to funding. Citation analysis is one of many performance indicators but has been largely set aside in the U. K. This paper describes the use of bibliometric data and examines the ?parochialism? of Northern irish research. Papers produced in Northern Ireland between the years 1981 to 1994 and listed with the ISI are used to exemplify the issues. The analysis indicates that some fields are underrepresented in the ISI database. Small research systems can also be significantly influenced by one or two individuals. Publication in a highly visible, Anglo-American, internationally refereed journal will enhance the citation rate. Northern Irish research has a relative lack of international impact, seemingly a function of topics and the journals used. While there is an increasing amount of joint authorship, particularly with the rest of the U. K. , relatively little collaboration has taken place with colleagues in the rest of Europe. Citation analysis is an important initial indicator of research impact, useful to establish questions and narrow an overall field of inquiry. .
