I've got a bit of a hack when it comes to sussing out which business books are the best. I look at the endorsement quotes and check if they are quotes from practitioners or quotes from other authors. 90%+ of the time they are from other authors and I know that likelihood of quality is low. On the other hand, quotes from practitioners (and especially ones successful in their field) are worth their weight in gold. Stripe Press books pass this test surprisingly often.
