Here are just a few quick links that relate to this subject:
Disabled Peoples International http://www.dpi.org/
International Disability Alliance http://www.internationaldisabilityalliance.org/
Seeing DisABILITIES from a Different Perspective (website by elementary school kids about changing perceptions of the disabled in their community) http://library.thinkquest.org/5852/homepg.htm
Anyone have anything else to add? Or maybe any books that shed some light on the topic?
