Abstract: The majority of author cocitation analysis (ACA) have relied on 
the Institute for Scientific Information (ISI) citation databases. ISI 
convention allows only the retrieval of papers that cite works of which 
the author is first or sole author. Non-primary authors (authors whose 
name appear in second or later position) will not be counted when 
assembling a cocitation frequency matrix. Therefore, this has been a 
methodological issue in ACA study. This paper empirically examines the 
impact of the ISI convention on the results of ACA. Previous research has 
addressed and shed light on some parts of methodological issues, but 
failed to address issues such as to what extent the use of different 
approach has resulted in different outcomes in terms of actual 
intellectual structure of a given academic discipline. Using our data and 
cociation matrix generation systems, we compare the differences in the 
process and outcomes of using different cocitation matrices. Our study 
concludes that all author based ACA is better than first author based ACA 
to capture all influential researchers in a field. It also identifies more 
research subspecialties. Finally, all Author based ACA and first author 
based ACA produce little differences in stress values of MDS outputs.
