Mani thoroughly analyzes a diverse body of research and demonstrates its relevance to automatic text summarization, and he presents this information in an extended, or organized format. As a first step toward providing a systematic introduction to this increasingly important and rapidly evolving field, this book represents a valuable contribution to the literature.

For researchers in the field of machine translation, this book provides a sufficient introduction to summarization to enable them to begin work in cross-lingual summarization.

Since this is the only textbook in its field, it will probably become required reading for new researchers, who will assume that it provides a full and balanced view...the book certainly provides a timely and informative overview of automatic summarization, and all researchers with an interest in this important field will wish to have it on their bookshelf.
