Reviews "...the book should be warmly welcomed and widely read. I shall frequently want to refer to it myself, and it will be particularly valuable to students learning about the subject. The latter advantage is especially important, given that most undergraduate courses in chemistry seem to ignore polymorphism, in spite of the fact that it is a ubiquitous phenomenon and is of critical industrial importance. The text of the book is generally clearly written and the illustrations are very helpful. The index is useful and the table of contents is very clearly set out. I recommend the book to a wide range of readership in the pharmaceutical industry and in academia - indeed, to all chemists interested in the characterization of solid organic compounds."
