Criteria what makes a good Website?

[Libby Whitcomb]

Hi
 I am looking for articles/ Websites that contain criteria
 about what makes a Web site effective? Either from a
 developers standpoint or the person who views the web site. 
I need documentation that I can show others about what factors 
make a Web site effective.  Are there standards similar to how a
 librarian evaluates a book source?
 I would appreciate any help on this question. Thank you,
I receive Web4Lib in digest format so I would appreciate direct
e-mail responses. 
Thank you,
