""There is a palpable sense of excitement from the editors of each volume that this is a critical period in the development of the field. The four volumes are edited by leading scholars in the field, who have carefully selected the volumes' contributing authors for their ability to summarise their topics succinctly, and tease out the issues that are likely to be the focus of research in the coming period. As with previous editions, this new edition of the Handbook will be a lodestar for practitioners and researchers in the field.""-Diane FitzMaurice, Library Information Supervisor, Department.
