The resources listed here inform my experience and work to date. Inclusion of a resource does not mean I accept all information from the source as gospel, but rather that I find some elements pertinent to understanding sustainability and finding effective paths towards a better world.

The categories I have used to classify these sources are not exclsuive and in some cases I have chosen to put a source in more than one category. I will endeavor to keep this list up to date as the field is growing rapidly. A special recognition to the Pelican Web site that is developed and managed by Dr. Luis Guitierrez. He covers the intellectual underpinnings of sustainability as well as any that I have seen. One can subscribe to his monthly Mother Pelican: A Journal of Sustainable  Human Development.
