Abstract: Some years after the publication of Vol. III/11 and its supplement III/18 dealing with elastic, piezoelectric, pyroelectric and optical properties of crystals, a complete recompilation of the data of these volumes and of new data was performed. Because of the growth of this subject matter it was found convenient to divide the material into four volumes, III/29a and b for the low frequency properties and III/30a and b for high frequency propertiesof dielectric crystals. The first subvolume III/29a contains exclusively second and higher order elastic constants including temperature and pressure coefficients.

Abstract: While vols. III/29 A, B (published in 1992 and 1993, respectively) contain the low frequency properties of dielectric crystals, in vol. III/30 the high frequency or optical properties are compiled. The present and first subvolume 30 A contains piezooptic and elastooptic constants, linear and quadratic electrooptic constants and their temperature coefficients, and relevant refractive indices. Subvolume 30 B will cover second and third order nonlinear optical susceptibilities. For the reader's convenience an alphabetical formula index and an alphabetical index of chemical, mineralogical and technical names for all substances of volumes 29 A, B and 30 A are included.

Abstract: Volume III/7 contains structure data on those compounds which contain at least one of the elements F, Cl, Br, I, O, N, and P and cannot be called "organic". The structure data of the remaining inorganic compounds and the elements are dealt with in volumes III/6 and III/14, while the organic compounds are treated in volumes III/5 and III/10. The systematic arrangement is based on the anions ordered according to "key elements", since this system allows the arrangement of the crystal structure data in such a way that both chemical and crystallographical relationships can be recognized. Structure data are compiled as completely as possible for all inorganic substances, where crystal structures have been examined by means of Xray, neutron, and electron diffraction,and for which at least the lattice constants have been determined.
