Dear colleagues, 
 
In my series of programs for use in class, I added one which generates a
coauthor network as a Pajek file from a set of documents downloaded from the
ISI databases at the Web-of-Science. The program can be found at
http://www.leydesdorff.net/software/coauth/index.htm. 
 
In addition to a co-occurrence matrix, a cosine-normalized matrix is
generated and the asymmetrical matrix of documents versus authors. This
latter matrix can be used for processing in SPSS. The variable names
correspond with the first ten characters of the name of the respective
author. I advice to use the cosine-normalized matrix (cosine.dat) for the
visualization. This one is in the Pajek format. The size of the node can be
set (within Pajek) proportional to the logarithm of the number of
authorships in the data.
 
With best wishes, 
 
 
Loet
