    Abstract
    Leydesdorff, in his 1998 paper 'Theories of citation?', addresses the history of citations and citation analysis, and the transformation of a reference mechanism into a purportedly quantitative measure of research impact/quality. Examines different facets of citations and citation analysis, and discusses the validity of citation analysis as a useful measure of research impact/quality
