Abstract

Evaluates current research into bibliographic relationships sparked off by B.B. Tillett's taxonomy of bibliographic relationships (LRTS 35(1991) no.4, S.393-405) and R.P. Smiraglia's taxonomy of the derivative bibliographic relationship (PhD dissertation, Chicago Univ., Graduate Library School, 1992). These researches provide the context for a discussion of recent research and standards work. Reevaluates research on the sequential relationship drawn from work conducted on periodicals and the implications of that research is applied to cataloguing system design. Evaluates the conceptual designs proposed by researchers such as G.H. Leazer and M. Gorman's and uses them in a critique of the USMARC format for bibliographic description

Abstract

Wilson stated that the work of providing bibliographic services is political in nature because catalogers have to adjudicate amongst the demands made for various forms of control by different communities. Although he did not address the work of the Documentalists directly, his claim is an implicit refutation of their universalist claims. Their efforts were to bring all the world's knowledge together, organize it under a single principle, and make it available to an undifferentiated global community. The concept of "universality" is examined in the context of bibliographic services, looking at claims regarding the collection of knowledge, users, and access.

Abstract

In this paper I describe a conceptual design of a bibliographic retrieval system that enables more thourough control of bibliographic entities. A bibliographic entity has 2 components: the intellectual work and the physical item. Users searching bibliographic retrieval systems generally do not search for a specific item, but are willing to retrieve one of several alternative manifestations of a work. However, contemporary bibliographic retrieval systems are based solely on the descriptions of items. Works are described only implcitly by collocating descriptions of items. This method has resulted in a tool that does not include important descriptive attributes of the work, e.g. information regarding its history, its genre, or its bibliographic relationships. A bibliographic relationship is an association between 2 bibliographic entities. A system evaluation methodology wasused to create a conceptual schema for a bibliographic retrieval system. The model is based upon an analysis of data elements in the USMARC Formats for Bibliographic Data. The conceptual schema describes a database comprising 2 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. Bibliographic relationships constitute the logical strucutre of the database

Abstract

To contribute to the development of a sophisticated control of bibliographic works research must be build on the growing understanding of the nature of the work and the constitution of bibliographic families. The present study was designed to address the following in the context of a global bibliographic database: OCLC's WorldCat: the proportion of works that are members of bibliographic families; the size of each family; bibliographic characteristics that can be associated with the existence or extent of derivative bibliographic relationships; the frequency with which each type of relationship appears; and the complexity of bibliographic families. A sample of bibliographic families was constructed. Results indicate that a core of works of similar character constitute the bibliographic population of American academic and research libraries (OCLC members). It seems that the canon of derivative works is greater in the academic sphere than in the bibliographic universe represented by OCLC at large. The size of a bibliographic family seems to be related to its popularity or its canonicity. Discipline, form, and genre all fail to demonstrate any influence on derivation of works. Further study of specific segments of the bibliographic universe, for instance the literature of particular disciplines, is clearly called for. The purpose of this research is to contribute to the development of a sophisticated control of bibliographic works and families. In particular, this research is designed to build on our growing understanding of the nature of the work and the constitution of bibliographic families

Abstract

A textual identity network is a set of documents that share common semantic or linguistic content. For example, the textual identity network of Ben-Hur includes the progenitor work, translations, screen play adaptations, and film performances. A network might also include successively numbered editions, simultaneous editions published in various countries, and other derivative forms. This network expresses how a work evolves over time and through a variety of media. Evolving textual identity can be expressed as a set of relationships among the members of the network. Several taxonomies of intertextual associations have been developed for use in information retrieval systems. The individual documents (books, films, computer files, etc.) contained in a textual identity network can be associated through a number of pairwise relationships, and the network can be studied as a system. This basic pattern makes textual networks ideal candidates for study using network analysis techniques, allowing summary measures that characterize networks. Topological indices provide high-level measures of network structure. This paper concludes on a discussion of how topological indices might be used in document retrieval
