The book contains 30 descriptive chapters dealing with a specific language contact situation. The chapters follow a uniform organisation format, being the narrative version of a standard comprehensive questionnaire previously distributed to all authors. The questionnaire targets systematically the possibility of contact influence / grammatical borrowing in a full range of categories. The uniform structure facilitates a comparison among the chapters and the languages covered. The introduction describes the setup of the questionnaire and the methodology of the approach, along with a survey of the difficulties of sampling in contact linguistics. Two evaluative chapters, each authored by one of the co-editors, draws general conclusions from the volume as a whole (one in relation to borrowed grammatical categories and meaningful hierarchies, the other in relation to the distribution of Matter and Pattern replication).
