The Laws of Etiquette is a classic business skills/etiquette guide text.

The best of us get on one another's nerves, even under ordinary conditions, and it takes infinite pains and self-control to get through a trying day in a busy office without striking sparks somewhere. If there is a secret of success, and some of the advertisements seem trying to persuade us that it is all secret, it is the ability to work efficiently and pleasantly with other people.

Every man is naturally desirous of finding entrance into the best society of his country, and it becomes therefore a matter of importance to ascertain what laws of etiquette are demanded for admittance.
