The Conflict Resolution Information Source website --
CRInfo (pronounced "See Our Info") stands for "conflict resolution information source."
It is a FREE service, funded by the William and Flora Hewlett Foundation.
As a "linking" site, their staff of editors maintains a keyword-coded catalog of over 20,000 Web, print, and organizational resources, as well as event listings and other conflict resolution-related resources.
I just found it and it seems full of interesting sites to look at for mediation information.
