I purchased this book and several others to review for the Civil PE exam and California's special seismic exam. Although it's a fairly slim volume, it contains exactly the information you need to master in order to do well on the seismic exam--no more, no less. Also, since it has copies of the UBC tables needed for the exam questions, you could actually use it during the exam as a reference instead of buying the UBC, which is much more expensive. Even though I had both, I found it more convenient to use this book during the exam. P.S. to Mr. Lendvay: I passed.
