How do I find people on the Internet?

CCSO/CSO

CCSO (often shortened to CSO) is another search tool found at many universities and large organizations. CCSO stands for Computing and Communications Services Office at the University of Illinois, Urbana- Champaign, which is where the directory and search tool was developed.

CSO allows the user to search for a person's name, e-mail address, department, etc. The CSO directory will return any information available for the person or department, and often includes phone numbers and e-mail addresses.
