The conference proceedings for "Sovereignty symposium 2007 : making medicine" (2007) provide a wealth of information on the Model Tribal Secured Transactions Act. The Act itself is provided, along with analysis, sample tribal codes/regulations and sample tribal compacts (or intergovernmental agreements). Much of the information is reprinted with permission from the National Conference of Commissioners on Uniform State Laws and can be accessed at the NCCUSL's web site.
For more information, go to the National Indian Law Library's online catalog at http://nillcat.narf.org/ Then type "security law" into the Subject Terms field.
