Important Disclaimer: Broken links are the bane of Internet-supported resource sites, and the current site has not escaped this problem. A large number of broken links have been removed from this site. Given pressing other obligations, a time-consuming search for their possible replacements is not possible. It is hoped that visitors to this site will nevertheless find the remaining working links of some use for their purposes.

Some Early Individual Researchers

Important Disclaimer: Research on social network formation is now so extensive it is impossible to keep the links below either current or complete. These links were last thoroughly updated in 2009 and can be viewed as an historical record of some early researchers in this area.
