The first edition filled the gap of practical information on the analysis of soil strength and slope stability, which, compared to other areas of geotechnical engineering such as foundation design, was lacking despite the importance of the topic in construction. The new edition continues to present the state-of-the-art in soil strength analysis through clear and concise language, practical examples, and a lack of extraneous theory which can distract from the application.  The book discusses the use of software in analysis, but cautions against using the software as a black box, and gives the reader both the background to understand what the software is doing, as well as several methods for figuring the analysis manually (charts, formulas, etc.) so the reader is able to verify results given by the software.
