The first text reviews a book titled "Tables of Experimental Dipole Moments" by A.L. McCLELLAN, published in 1963. This book is the only comprehensive collection of experimental dipole moment values up to 1962, covering about 6000 compounds with 2178 bibliographic references. The values are organized into three tables: mineral compounds, organic compounds, and compounds with undefined formulas. Each entry includes the study method, solvent, and temperature. The book is well-organized and easy to consult, making it a valuable resource for crystallographers comparing X-ray diffraction results with other methods. The second text reviews "Silicate Science, Vol. II: Glasses, Enamels, Slags" by W. EITEL, published in 1965. This volume supplements the 1954 edition, focusing on the period from 1952 to 1962. It is divided into five parts, with this volume covering silicate glasses, industrial glass and enamels, and industrial slags. The content is extensive, with over 2000 literature references, and includes detailed discussions on properties, constitution, and technical aspects. The reviewer praises the author's comprehensive approach and the book'sencyclopedic value, while suggesting a more specific title for future volumes to avoid confusion. The third text reviews "Transactions of the American Crystallographic Association, Vol. I (1965), Proceedings of the Symposium on 'Accuracy in X-ray Intensity Measurement'" published in 1966. This volume complements the A.C.A.'s Monograph Series by providing timely surveys of rapidly changing topics in crystallography. It includes six papers presented at a symposium in 1965, covering topics such as absolute intensity measurement, the R-factor, extinction corrections, and background factors in single-crystal diffraction.The first text reviews a book titled "Tables of Experimental Dipole Moments" by A.L.
