Grey Literature

[Grant Barrett]

Interesting phrase and idea in the form of "grey literature."

>From http://www.mcb.co.uk/ijgl.htm

"The International Journal on Grey Literature (IJGL) is a forum for
discussion of ...  grey literature in a global context.  Grey literature is that produced by all
levels of government, academia, business and industry in print and
electronic formats, yet is not controlled by academic publishers."

and 
"By definition, Grey Literature is the information and resources that do not
categorically fall into what is available via standard traditional or
commercial publishing channels."
