Title: A conceptual plan for the description and control of bibliographic works

Abstract: This dissertation is a conceptual design of a bibliographic retrieval system that enables more thorough control of bibliographic entities. A bibliographic entity has two components: the intellectual work and the physical item. The atomic unit of contemporary bibliographic retrieval systems is a description of the item. The work is described only implicitly by collocating, or gathering together, descriptions of bibliographic items. This method has resulted in a tool that does not include important descriptive attributes of the work, as for example, information regarding its history, its genre and intellectual form, and especially its bibliographic relationships. A bibliographic relationship is an association between two bibliographic entities. This dissertation is part of a general research effort to re-conceptualize the library catalog as a bibliographic database.

A system evaluation methodology was used to create a conceptual model for a bibliographic retrieval system. The model is based upon an analysis of data elements in the USMARC Formats for Bibliographic Data. A conceptual schema for the proposed bibliographic retrieval system is created in the design stage of the system evaluation.

The conceptual schema describes a database comprising two separate files of bibliographic descriptions, one of works and the other of items. Each file consists of individual descriptive surrogates of their respective entities. The specific data content of each file is defined by a data dictionary. Data elements used in the description of bibliographic works reflect the nature of works as intellectual and linguistic objects. The descriptive elements of bibliographic items describe the physical properties of bibliographic entities. Data elements for the control of items describe the physical format of the bibliographic entity.

Bibliographic relationships constitute the logical structure of the database. The structure of the bibliographic universe, expressed by a variety of bibliographic relationships, is captured and modelled in the bibliographic control tool. This is accomplished by linking together the individual descriptive surrogates of both works and items according to their relationships.
