The Couch Biology Library, Botany Section maintains a current collection of about eighty nursery plant and seed catalogs. Arranged by business name and shelved behind the circulation desk, these materials do not appear in the online catalog. They may be checked out at the discretion of the librarian and library assistant. In addition, the library owns a number of resources shelved in the Reference Collection to assist patrons in locating nurseries and plant materials. Ask staff for assistance.
