Title
Citation analysis and the development of science : a case study using articles by some Nobel prize winners
Source
Journal of the Association for Information Science and Technology. 65(2014) no.2, S.281-289

Abstract
Using citation data of articles written by some Nobel Prize winners in physics, we show that concave, convex, and straight curves represent different types of interactions between old ideas and new insights. These cases illustrate different diffusion characteristics of academic knowledge, depending on the nature of the knowledge in the new publications. This work adds to the study of the development of science and links this development to citation analysis.
