**Theory of Elasticity by S. P. Timoshenko and J. N. Goodier (3rd ed., McGraw-Hill, 1970)** This book, reviewed by H. Norman Abramson, is a significant revision of the original work, now nearly three times larger than the first edition. The third edition, prepared by Norman Goodier before his passing, retains the clarity and depth of the original while incorporating new developments. Key revisions include expanded discussions on end effects, Saint-Venant's principle, edge and screw dislocations, photoelastic methods, and complex potentials for two-dimensional problems. The chapters on thermal stress and wave propagation have been extensively rewritten to reflect recent advancements. The book is well-suited to serve future generations of students and engineers. **Modern Control Theory and Computing by D. Bell and A. W. J. Griffin (McGraw-Hill, 1964)** Reviewed by K. J. Astrom, this book aims to bridge the gap between theory and practice in control engineering. It covers classical linear control theory, Lyapunov techniques, and various types of computers. The book also introduces stochastic processes, identification problems, and adaptive systems. While the treatment is expository and includes programming examples, it could benefit from more detailed discussions on Kalman filtering and linear stochastic control theory. The reviewer believes the book effectively communicates the potential of modern control theory to practicing engineers. **Thermodynamic Properties of Perfect Gases for Temperatures up to 6000 deg K by H. D. Baehr, H. Hartmann, H. C. Pöhl, and H. Schömaker (John Wiley & Sons, 1964)** Reviewed by J. Kestin, this book provides reliable data on the thermodynamic properties of gases at low pressure. The authors' reputation ensures accuracy, and the tables are well-presented on good-quality paper. The volume covers equilibrium properties for 30 gases, making it a valuable resource for readers needing such data. The book's graphical excellence and relatively low price make it an attractive option for those in need of this information.**Theory of Elasticity by S. P. Timoshenko and J. N.
