The present volume is a computer-based extension and complete revision of the symmetry tables of the two previous series of International Tables, the Internationale Tabellen zur Bestimmung von Kristallstrukturen (1935) and the International Tables for X-ray Crystallography (1952).^{1}
The main part of the volume consists of tables and diagrams for the 17 types of plane groups (Part 6 ) and the 230 types of space groups (Part 7 ). The two types of line groups are treated separately in Section 2.2.17 , because of their simplicity. For the history of the Tables and a comparison of the various editions, reference is made to the Preface of this volume. Attention is drawn to Part 1 where the symbols and terms used in this volume are defined.
The present part forms a guide to the entries in the space-group tables with instructions for their practical use. Only a minimum of theory is provided, and the emphasis is on practical aspects. For the theoretical background the reader is referred to Parts 8–15 , which include also suitable references. A textbook version of space-group symmetry and the use of these tables (with exercises) is provided by Hahn & Wondratschek (1994).
