This is an edited collection comprising of an introduction and seven self-contained chapters, each covering a different aspect of contemporary information retrieval (IR). Each chapter stands alone and includes a conclusion and extensive references at the end of the chapter, and the book is well indexed, as one would expect. Each chapter provides a valuable insight and expert view on an area within the broad IR topic. While the scope of the book is certainly diverse, what it does is give the reader an excellent overview of research and future directions in the field of IR. Although this book is aimed predominantly at postgraduate students with an interest in information retrieval, and specifically those undertaking dissertations at Master's or PhD level, it certainly has wider appeal and relevance for LIS students, academics, researchers, and those involved in the design of IR systems.
