Keeping Duplin Core Simple
Reality is messy. Individuals perceive or define objects differently. Objects may change over time, morphing into new versions of their former selves or into things altogether different. A book can give rise to a translation, derivation, or edition, and these resulting objects are related in complex ways to each other and to the people and contexts in which they were created or transformed. Providing a normalized view of such a messy reality is a precondition for managing information. From the first library catalogs, through Melvil Dewey's Decimal Classification system [1] in the nineteenth century, to today's MARC encoding [2] of AACR2 cataloging rules [3], libraries have epitomized the process of what David Levy calls "order making" [4], whereby catalogers impose a veneer of regularity on the natural disorder of the artifacts they encounter.
