We live in an age of encyclopedias. Our bookcases are packed with tomes of knowledge and information, both general and specialized, and many of them even come in cd-roms these days. Books with titles such as 'All you need to know about [whatever]', and 'How to [whatever]', sell like hot cakes. I presume that the main reason for their popularity is that in our rushed lifestyle we need quick fixes. Vast repositories of knowledge have also become available in TESOL; the few titles in the references section below give you but a taste of the encyclopedias and introductory textbooks available in academic bookshops and libraries. While suppressing a yawn, the reviewer begins to wonder what makes any of these titles unique and competitive. Aren't they mere clones of one another? More specifically, aren't I supposed now to review a book which shares too many features with other titles to make it distinctly di¤erent? The answer is no: The Cambridge Guide is di¤erent! First, let me examine its structure in some detail. The book consists of 30 chapters, flanked by an introduction and a postscript. The main text is followed by a 200-item glossary, and a reference section covering some 1,500 titles. The Cambridge Guide is the product of 33 authors, including the two editors who, in addition to the Introduction, wrote one chapter each. All the contributors are eminent researchers in their field—a necessary, albeit not a suªcient, condition for producing a useful textbook.
