Thus, catalogers prepare a description of an item, assign subject headings, determine a shelf location using a classification system, provide a link to the electronic item, if appropriate, and code that information with both MARC tags or metadata so that it may be displayed in local online catalogs and, if the library catalogs with OCLC, in WorldCat. Each element of the cataloging process is addressed in other tabs of this Guide, along with sources for the cataloging tools needed.
Cataloging ethics is described as the "principles and values that provide an intentional decision-making framework for those who work in cataloging or metadata positions."
