General Stud Book
In 1791, James Weatherby published "Introduction to a General Stud Book", which was an attempt to collect pedigrees for the horses racing then and that had raced in the past. 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. Volume one was revised many times, the most important being in 1803, 1808, 1827, 1859 and 1891.
