Abstract: This article compares two maps of science that are built from 
different, but highly representative sets of the world-wide scientific 
literature. The analysis in this article extends existing work in this 
area in three major ways First, we provide quantitative comparisons of the 
ISI and Scopus databases for 15 areas of science. Second, we illustrate 
how these differences have an impact on the resultant map of science. 
Third, we argue that these differences do not affect the fundamental shape 
and structure of science; the differences create local differentiation and 
improve our understanding of local relationships. We conclude with a 
discussion about the value of generating a convergent map of science.
