General Stud Book

The General Stud Book is a breed registry for horses in Great Britain and Ireland.

More specifically it is used to document the breeding of Thoroughbreds and related foundation bloodstock such as the Arabian horse.

It was filled with errors and was not at all complete, but it was popular and led in 1793 to the first volume of the General Stud Book which had many more pedigrees and was more accurate.

[3] The General Stud Book has been owned by Weatherbys ever since; the two horse racing authorities that cover the United Kingdom, the British Horseracing Authority in Great Britain (historically the Jockey Club) and Horse Racing Ireland for all of the island of Ireland, including Northern Ireland, do not maintain the registry.

[4][5][6] This differs from the American Stud Book which is owned by the United States Jockey Club.
