Oklahoma Legal Research is the first book focused exclusively on how to research Oklahoma law. Oklahoma Legal Research: examines resources and research methods for all types of Oklahoma primary law, secondary law, and practice materials with chapters on researching Oklahoma statutory, regulatory, and case law; includes a chapter on researching tribal law for Native American tribes located in Oklahoma; discusses how to do historical statutory research to locate the increasingly available legislative history materials for Oklahoma statutes; and covers resources and methods in both print and online formats, with visuals included to assist the researcher. This text has been written for legal researchers of various levels of experience and training. For those just learning the intricacies of legal research, it explains the basic processes and introduces the novice to the most important sources of Oklahoma and Native American tribal law. It also briefly discusses analogous materials in federal law, so that the less experienced researcher can better see the parallels between state and federal research. Experienced researchers will also benefit from having a text that brings together both print and online sources of Oklahoma law and that will assist them in determining which of those sources are better suited to accomplishing a particular research task.
