Countries in which Arabians are bred on a large scale such as Poland and Spain are represented as are countries breeding Arabians on a small scale such as Belize. Stud books from both government registries and private registries reside in the collection. Books covering numerous subject areas and dating from the 1700s are included in the collection. Many are rare first editions or collectors' item. Breed history, training, showing, travel, poetry, and bloodlines are among the topics covered.
Many books are rare and valuable as much for their aesthetics as for their content.
One of these is The Celebrated Romance of the Stealing of the Mare by Abu Obeyd. This publication has uniquely beautiful printing and is one of the rarest holdings in the collection. In addition to the more common types of materials, the W. K. Kellogg Arabian Horse Library collects a number of other items. A file is kept of newletters from Arabian horse clubs throughout the United States. There is a file for farm brochures from Arabian horse breeders from around the world.
