The Jockey Club was formed in 1894 and assumed responsibility for maintaining The American Stud Book two years later. The stud book ensures the correct pedigree and identification of every Thoroughbred and, as such, is essential to the integrity of Thoroughbred breeding and racing.

North American owners and breeders register approximately 37,000 Thoroughbreds annually with The Jockey Club. An increasing number are doing so through the convenience of the Internet utilizing The Jockey Club's Interactive Registration^TM (IR). This is the quickest and easiest way to complete and submit the requirements for registration and naming of foals, including submission of digital photographs.

One of the most unique and popular features of IR is the ONLINE NAMES BOOK, which lets users browse The Jockey Club's database of approximately 430,000 names in active use. The Online Names Book is accurate up to the minute it is accessed, meaning that owners and breeders who consult the Online Names Book have a greater chance of securing a desired name for their Thoroughbred than those who just submit names that may or may not be available.
