Structure Reports are published annually and are divided into two main sections: metals and inorganic compounds. The format of information in individual reports is: names, formulae, papers reported, unit cell and space group data, details of analysis, atomic positions, interatomic distances and angles, description and discussion of the structure (with diagrams), and additional references. The subject index is based on the names of the substances as given in the headings of the individual reports. Each volume also has an author index. This cumulative index is published as a separate volume. The Reports make the search through hundreds of journals unnecessary, as each volume gives the essence of one year’s worldwide literature on crystal structure determinations.
