There is no other reference work on psychology and the law, so libraries supporting curricula in this area may consider purchasing. But because this field of study is still in its infancy, and it remains to be seen whether it will grow into something major, this set is otherwise an optional purchase for most libraries.The interdisciplinary field of psychology and law appeals to students, psychological scientists, psychologist practitioners, and members of the legal and public policy professions, such as lawyers, judges, lawmakers, and other administrators of justice. This young field of research and practice is noted for its intellectual diversity, as it draws on all of the traditional subdisciplines of psychology and on various domains of law, legal practice, and public policy. Although this diversity is in many respects a very desirable feature, it creates many challenges as well. In particular, the breadth of research and practice contributes to a dearth of comprehensive reference sources and makes it difficult for individual students, scientists, and practitioners to keep current with the growing knowledge base outside of their individual areas of expertise.
