David Selden of National Indian Law Library has published “Researching American Indian Tribal Law” in the Colorado Lawyer.
An excerpt:
The ability to research tribal law is becoming increasingly important as 566 sovereign Indian nations and Alaska Native villages exercise their powers of self-governance. “Tribal law” comprises the laws developed by tribes or Indian nations, which apply within their territories and to their members. It can be a difficult area of law to research because few primary and secondary resources are published and made available to the public.
