This textbook is a complete and clear introduction to the field of crystallography. It includes an extensive discussion on the 14 Bravais lattices and their reciprocals, the basic concepts of point- and space-group symmetry, the crystal structure of elements and binary compounds, and much more. The purpose of this textbook is to illustrate rather than describe "using many words" the structure of materials. Even readers who are completely unfamiliar with the topic, but still interested in learning how the atoms are arranged in crystal structures, will find this book immensely useful. Each chapter is accompanied by exercises designed to encourage students to explore the different crystal structures they are learning about. The solutions to the exercises are also provided at the end of the book.
