This book represents one part of the continued development and expansion of Functional Requirements for Bibliographic Records. It contains a further analysis of the characteristics of various entities which are in the focus of standard data (persons, families, corporate bodies, work, expression, manifestation, item, concept, object, event and place), the definitions under which these entities are known and the standard search entries which the cataloguers create for these entities.
