Mcgraw Hill

It has been 30 years since the first edition of this encyclopedia was published. Over this span of time, the terminology in science and technology has expanded at a rapid rate, resulting in the addition of some 5,000 new terms in each edition. The sixth edition continues that expansion and now has some 110,000 terms and 125,000 definitions, accompanied by 3,000 black-and-white illustrations. The format continues as in the past, with letter-by-letter alphabetization. Synonyms, acronyms, and abbreviations are given within the definition. Pronunciation of each and every term continues to set this dictionary apart from other science and technology dictionaries. It is a large, heavy volume that lies flat when open. It may be time for the publisher to consider a two-volume work for ease of handling by the patron.
