There is a global blog on panarchy at Panarchists.wordpress.com.

Panarchy article in Wikipedia.

The premier panarchy website is panarchy.org, assiduously maintained by Gian Piero de Bellis of Switzerland.

The article in which the term "panarchy" was coined, available on panarchy.org in the original French, or translated in English, German, Spanish, or Portuguese, was written by Paul Emile de Puydt, a Belgian botanist, in 1860.

Not interested in what a Belgian had to say in 1860? How about an American in 2003? Gene Callahan, author of "Economics for Real People", may have never heard the word "panarchy", but he advocates for it persuasively in "The Right to Walk Away".
