The Kelley Blue Book is the largest vehicle evaluator in the United States. The Blue Book provides pricing and information for new and used vehicles. Kelley Blue Book is headquartered in Irvine, California.
The Kelley Blue Book Company was established in 1918 as part of a Los Angeles, California car dealership named the Kelley Kar Company. It was founded by Les Kelley.
The Kelley Blue Book was mostly a trade publication until the early 1990s, when a consumer edition was developed to determine the value of vehicles.
The Blue Book reports market value prices for used and new automobiles and other types of motorised methods of transportation. The book provides retail value, trade-in value and suggested private party prices.
Since 1995 Kelley Blue Book evaluations have been available online at KBB.com. Since its inception, KBB.com has become one of the most visited vehicle-related sites on the Web.
The company has registered "Blue Book" as a protected trademark in the United States and Canada. In recent years competing services such as Carfax, Manheim Market Report and Galves Wholesale Guide have been created.
