(Inorganic Crystal Structure Database) - world’s largest database for fully identified inorganic crystal structures; produced by FIZ Karlsruhe and currently containing more than 193,000 crystal structures. Updates made twice a year (in spring and in fall) with data taken from scientific journals and other sources.
The Protein Data Bank (PDB) archive is the single worldwide repository of information about the 3D structures of large biological molecules, including proteins and nucleic acids. The PDB archive is available at no cost to users. The PDB archive is updated weekly.
Contains information about experimentally-determined nucleic acids and complex assemblies.
Use the NDB to perform searches based on annotations relating to sequence, structure and function, and to download, analyze, and learn about nucleic acids.
The NDB was founded in 1992 by Helen M. Berman, Rutgers University, Wilma K. Olson, Rutgers University, and David Beveridge, Wesleyan University.

Basic Concepts of Crystallography by E. ZolotoyabkoWritten by an experienced university teacher, this textbook is based on the author's lectures, and is designed to answer students' questions rather than delving into obscure details. The well-balanced approach gives precedence to a visual, intuitive understanding, with only as much math as is necessary. The author covers the topic of symmetry in crystals from basic elements to physical properties, backed by numerous clear-cut illustrations and easy-to-read crystallographic tables. The result is a compact and self-contained treatment suitable for crystallography courses in physics, chemistry, materials science and biology - irrespective of the academic background.

International Tables for Crystallography, Volume D by A. AuthierInternational Tables for Crystallography is the definitive resource and reference work for crystallography and structural science. Each of the eight volumes in the series contains articles and tables of data relevant to crystallographic research and to applications of crystallographic methods in all sciences concerned with the structure and properties of materials. Emphasis is given to symmetry, diffraction methods and techniques of crystal-structure determination, and the physical and chemical properties of crystals. The data are accompanied by discussions of theory, practical explanations and examples, all of which are useful for teaching. Volume D is concerned with the influence of symmetry on the physical and tensor properties of crystals and on their structural phase transitions. This role is very important in many different disciplines of the science of materials such as crystallography, elasticity, solid-state physics, magnetism, optics, ferroelectricity and mineralogy, and Volume D deals with all these aspects in a unified way. The volume is divided into 3 parts: Part 1: Introduces the mathematical properties of tensors and group representations and gives their independent components for each of the crystallographic groups. Part 2: Devoted to the symmetry aspects of excitations in reciprocal space: phonons, electrons, Raman scattering and Brillouin scattering. Part 3: Deals with the symmetry aspects of structural phase transitions and twinning. A prominent feature is the joint description of twinning and domain structures, which are usually presented in completely separate ways in handbooks of physics and mineralogy.
