This paper examines whether different co\u2010citation counting methods produce different results in author co\u2010citation analysis studies of the intellectual structure of research fields, and if so, in what ways they differ. Our results indicate that, with respect to the major specialties and how they relate to each other, the intellectual structures of the Information Science field identified through author co\u2010citation analyses based on different co\u2010citation counting methods are largely equivalent, but when it comes to detailed structure, results differ in a number of ways. In particular, classic first\u2010author co\u2010citation analysis appears to better represent the theoretical and methodological aspects of the field whereas all\u2010author co\u2010citation analysis favors more recent empirical studies, and picks out some tightly collaborative research groups or projects. We experiment with using meaningful diagonal values in a co\u2010citation matrix rather than using statistically generated values, and observe favorable results. We also employ a new visualization technique for reporting the results of a classic author co\u2010citation analysis, using a bipartite graph that represents all the information in the factor matrix of specialties and author loadings as author and factor vertices connected by edges with loadings as similarity\u2010measure line values, laid out algorithmically in two dimensions.<\/jats:p>","DOI":"10.1002\/meet.1450440262","type":"journal-article","created":{"date-parts":[[2008,10,29]],"date-time":"2008-10-29T15:34:53Z","timestamp":1225294493000},"page":"1-12","source":"Crossref","is-referenced-by-count":3,"title":["All\u2010author vs. first\u2010author co\u2010citation analysis of the Information Science field using Scopus"],"prefix":"10.1002","volume":"44","author":[{"given":"Dangzhi","family":"Zhao","sequence":"first","affiliation":[]},{"given":"Andreas","family":"Strotmann","sequence":"additional","affiliation":[]}],"member":"311","published-online":{"date-parts":[[2008,10,29]]},"reference":[{"key":"e_1_2_7_1_1","doi-asserted-by":"publisher","DOI":"10.1002\/asi.10242"},{"volume-title":"Multivariate Data Analysis","year":"1998","author":"Hair J.
