The valuable information in Pearson's Handbook is now more affordable in a handy desk reference. 27,686 entries of the highest quality crystal data, representing 27,686 different compounds. Structure type given for all entries. 54 per cent of entries include the coordinates of the atoms. 605 entries are 'filled-up' structure 1,730 structure types have been assigned by the editor 6,426 belong to berthollide compounds. Data included up to 1995 (6-year update to the Second Edition 12-year update to the First Edition). Full 167-page structure-type index (with all its representatives). Entries include full information, as in the Second Edition. Comprises all the international literature from 1913 to 1995. Includes detailed crystallographic data for unary, binary and ternary phases, excluding halides and ternary (or quaternary) oxides. Fully revised and updated. Covers more than 27,000 compounds, with all data critically evaluated. Includes the following improvements over the original Pearson's. Additional literature years between 1989 to 1995 have been covered completely and comprehensively, based on searches of more than 130 journals and more than 10,000 abstract pages per year. Entries contain additional information, such as calculated density, color, more detailed diffraction data, standard deviation of unit cell dimension(s), point-set symmetry, and full reference, including publication title. All entries and structure types have been computer checked for consistency and correctness. All crystallographic data are now given in the standard setting according to the International Tables for Crystallography. Include a Six-Year Update of the Data in The Second Edition.

Since the discovery of X-ray diffraction in 1913 over 100 000 different inorganic substances (also called compounds or phases) have been structurally characterized. The aim of this reference work is to provide the researcher with a comprehensive compilation of all up to now crystallographically identified inorganic substances in only one volume. All data have been processed and critically evaluated by the "Pauling File" editorial team using a unique software package. Each substance is represented in a single row containing the following information: - Alphabetically sorted chemical elements - Standardized chemical formula - Prototype (structure type): type-defining compound, Pearson symbol, space group number - Hermann-Mauguin symbol for the space group - Unit cell dimensions- Color - Density calculated from the chemical formula and unit cell dimensions - Code indicating the level of structural studies (atom coordinates refined; no atom coordinates refined, but prototype assigned; only cell parameters determined) - Reference number

In the 1970s Landolt-Börnstein published a series of volumes containing crystallographic data for organic (III/5 Str- ture Data of Organic Crystals), intermetallic (III/6 Structure Data of Elements and Intermetallic phases) and inorganic compounds (III/7 Crystal Structure Data of Inorganic Compounds).

Volume 43 of Group III deals with crystallographic data of both intermetallic and classical inorganic compounds, thus forming an update of the former Landolt-Börnstein volumes III/6 (Structure Data of Elements and Intermetallic Phases) and III/7 (Crystal Structure Data of Inorganic Compounds).
