Annual catalogues of registered bulls, cows and their progeny, created as a mode of tracing back the pedigrees of each animal. It was created by T.C Eyton, to prevent confusion when tracing the blood line of the cattle before purchase and/or breeding them. Each animal has a unique reference number to prevent name confusion. It also contains the names of breeders, and the bulls they have bred to check the quality of their stock.
Where the bulls numbers are given below they were present on the spine of the volume.
