About the Collection The OSU Seed and Nursery Trade catalogue collection contains over 2,000 items from 1832 to 1966. While the collection is most comprehensive in its representation of American catalogues from the 1940s, it contains many older examples from North America, Great Britain, and Holland, as well other European and Asian countries. Former agricultural librarian Laura Kelts compiled the collection from various sources in the 1960s and 1970s. At that time, it was stored in a locked room of the science area of the library, where space was at a premium. In 1986, the new Special Collections unit was formed and the collection was moved there, where it resides today. Seed and nursery trade catalogues are lists of seeds or plants available for sale.
