Paperback Introduction to Geotechnical Engineering Textbook! Used for undergraduate soil mechanics or geotechnical engineering courses. By Robert D. Holtz, William D. Kovacs, and Thomas C. Sheahan. Second edition. Published by Pearson. I was sent the Indian edition, but I used this for class in the US and I don't recall having any issues with it besides the page numbers being off. ISBN from Amazon: 9332507619 or ‎978-9332507616. In excellent used condition, minor cover wear, inside is like new.
