The American Aberdeen-angus Herd-book: Containing A Record Of Aberdeen-angus Cattle Approved And Admitted For Registry Under The By-laws Of The American Aberdeen-angus Breeders' Association; Volume 29

The American Aberdeen-Angus Herd-book, Volume 29, serves as a formal historical registry produced by the American Aberdeen-Angus Breeders' Association. Established in the late 19th century, these volumes were compiled to provide a standardized, authoritative record of pedigrees for the breed in the United States. They functioned as a critical administrative tool for farmers and livestock breeders, ensuring the purity and quality of the Aberdeen-Angus lineage during a period of significant agricultural expansion and breed refinement in the American Midwest.

The design of these volumes follows the utilitarian conventions of 19th and early 20th-century professional registries, focusing on clarity, accuracy, and ease of reference. Each entry provided a systematic documentation of a specific animal's ancestry, which was essential for maintaining the integrity of the registry under the association's by-laws. These books are widely regarded today as primary source documents for agricultural historians and genealogists tracking the development of livestock genetics in North America.
