I have written a research guide on my specialty, complementary currencies, that has been published by Fields of Knowledge at:
The Infography about Community Currencies
This is comprised of a short list of “superlative sources” and a somewhat longer list of other good sources on the subject.
The Infography appears to be a very good reference resource on a wide range of topics, and I suggest that you consult it when doing research on any subject and consider adding the following link to your blogs and web pages:
