Not strictly documents related, but the latest issue of D-Lib features a library using Wikipedia in a ethical way to raise awareness and usage of their digital materials:

Lally, Ann M., and Carolyn E. Dunford. "Using Wikipedia to Extend Digital Collections" D-Lib Magazine 13(5/6)(May/June 2007)(http://www.dlib.org/dlib/may07/lally/05lally.html)

The UW folks seems to have good before and after tables and graphs to demonstrate that it has been well worth for librarians to add quality library-based content to Wikipedia.

Anyone else in the documents world doing this besides UNT?
