The UDC and a botanical collection with special reference to the Botanical Library, British Museum (Natural History) Available to Purchase

The choice of a classification scheme is never entirely objective. One's past acquaintance with one or more of the major schemes, while training as a librarian, and/or in a work situation must have some influence on one's final decision. Before embarking on classing a library collection one should consider the relative merits of the various major schemes in relation to your user's requirements.
