In the U.S. Navy ""Wheel Books"" were once found in the uniform pockets of every junior and many senior petty officers. Each small notebook was unique to the Sailor carrying it, but all had in common a collection of data and wisdom that the individual deemed useful in the effective execution of his or her duties. Often used as a substitute for experience among neophytes and as a portable library of reference information for more experienced personnel, those weathered pages contained everything from the time of the next tide, to leadership hints from a respected chief petty officer, to the color coding of the phone-and-distance line used in underway replenishments.

In that same tradition, the new Naval Institute Wheel Books will provide supplemental information, pragmatic advice, and cogent analysis on topics important to modern naval professionals. Drawn from the U.S. Naval Institute's vast archives that has been accumulated for more than a century, the books will combine articles from the Institute's flagship publication Proceedings, selections from the oral history collection and from Naval Institute Press books to create unique guides on a wide array of relevant professional subjects.

Command is the pinnacle of leadership in a military organization. Navy Regulations define both the authority and the responsibility of command as ""absolute."" This Naval Institute Wheel Book provides practical guidance and advice that actual and would-be commanders can use to carry out that absolute authority. Included in this specially-selected collection is the experience of those who have commanded as well as the expectations of those who are commanded. Aspirants as well as practitioners will do well to exploit this selected survey of what Fleet Admiral Chester Nimitz described as the ""one purpose"" for entering the Navy.
