If you only need the buying answer, rental is still the cheaper short-term path. The current hardcover is close enough to rental and below the sampled clean new-print market to make ownership reasonable for readers who expect to keep using the book in later seismic or geotechnical work.

Rental is still the cleanest budget answer and that should be said plainly. But the ownership gap is not extreme, and the current hardcover is below the sampled new-print market and far below the sampled used market. For a technical graduate engineering reference, that is enough to make print a practical choice rather than an indulgence if you expect any later reuse.
What this book actually teaches
Geotechnical Earthquake Engineering is a technical reference built around seismology, site response, dynamic soil properties, soil-structure interaction, performance-based design, and the engineering logic needed to connect seismic demand to geotechnical behavior. This is not a light survey text. Readers often return to it when formulas, site-response assumptions, or design logic need to be checked again.
That long-tail usefulness is why the ownership question matters. If the book is only there to get you through one graduate course, rental is enough. If you expect continued work in earthquake engineering, structural design, or geotechnical practice, the current hardcover is priced well enough to justify keeping it.
Who should buy print and who should not
Choose rental if you need the lowest immediate cost and do not expect to reopen the book. Choose print if you are likely to revisit seismic geotechnical material in later design or professional work. The current hardcover is not the cheapest route, but it is competitive enough for long-term technical ownership.
