I've flipped through "Strength Training Anatomy" in the bookstore a couple of times and I'm currently reading "Starting Strength 2nd Ed." for the first time.
They're quite different.
"Starting Strength" is an extremely in-depth, text-heavy look at how to perform and coach the squat, bench and deadlift, and also contains somehwat shorter write-ups on assistance lifts such as the front squat, overhead press, powerclean and good morning.
"Strength Training Anatomy" is built around large illustrations showing the muscles involved in various lifts. It covers a lot of lifts, including many isolation movements. The text is fairly sparse.
"Strength Training Anatomy" is a good book if you want to visualize what muscles are working during various lifts. I expect it's okay for expanding your knowledge base if you don't know much about lifting (that's not meant to be a knock against you, it's just my general assessment).
But if you're looking to learn good technique inside and out, "Starting Strength" is in another league completely.
