Change is constant in legal research. Plucknett's work describes, for example, the modem textbook replacing published case reports as the most important form of legal literature. More recently, A.B.W. Simpson has argued that the law review article has displaced the treatise. Apart from these changes, the law itself has continued to embrace concepts from other disciplines and deal with facts and methodologies of an increasingly technological society.
