Abstract

Forty-five years have passed since Lubetzky outlined the primary objectives of the catalog, which should facilitate the identification of specific bibliographic entities, and the explicit recoguition of works and relationships amongthem. Still, our catalogs are better designed to identify specific bibliographic entities than they are to guide users among the network of potential related editions and translations of works. In this paper, we seck to examine qualitatively some interesting examples of families of related works, defined as bibliographic families. Although the cases described here were derived from a random sample, this is a qualitative analysis. We selected these bibliographic families for their ability to reveal the strengths and weaknesses of Leazer's model, which incorporates relationship taxonomies by Tillett and Smiraglia Qualitatice analysis is intended to produce on explanation of a phenomenou, particularly an identification of any palterns observed. Patterns observed in qualitative analysis can be used to affirm external observations of the same phenomena; conclusions can contribute to what is knoton as grounded theory-a unique explanation grounded in the phenomenon under study. We arrive at two statements of grounded theory concerning bibliographic families: cataloger-generated implicit maps among works are inadequate, and qualitative analysis suggests the complexity of even the smallest bibliographic families. We conclude that user behavior study is needed to suggest which alternative maps are preferable.

Abstract

ADEPT is a 5-year project whose goals are to develop, deploy, and evaluate inquiry learning capabilities for the Alexandria Digital Library, an extant digital library of primary sources in geography. We interviewed nine geography faculty members who teach undergraduate courses about their information seeking for research and teaching and their use of information resources in teaching. These data were supplemented by interviews with four faculty members from another ADEPT study about the nature of knowledge in geography. Among our key findings are that geography faculty are more likely to encounter useful teaching resources while seeking research resources than vice versa, although the influence goes in both directions. Their greatest information needs are for research data, maps, and images. They desire better searching by concept or theme, in addition to searching by location and place name. They make extensive use of their own research resources in their teaching. Among the implications for functionality and architecture of geographic digital libraries for educational use are that personal digital libraries are essential, because individual faculty members have personalized approaches to selecting, collecting, and organizing teaching resources. Digital library services for research and teaching should include the ability to import content from common office software and to store content in standard formats that can be exported to other applications. Digital library services can facilitate sharing among faculty but cannot overcome barriers such as intellectual property rights, access to proprietary research data, or the desire of individuals to maintain control over their own resources. Faculty use of primary and secondary resources needs to be better understood if we are to design successful digital libraries for research and teaching.

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

Politics is about the distribution of goods and risks. We can describe the distribution of goods, and we can also characterize those distributions as a kind of inequality. As a baseline definition of "politics of information" we mean the distribution of information goods across different populations. Despite a strong tradition of disciplinary focus in information science, much of the literature is still given over to fairly simple notions of social form and structure. A nascent knowledge organization practice dedicated to social difference is explicitly motivated by justice and nomenclature. Not only is knowledge organization a tool of cultural hegemony, but also it can be read as a product of cultural ordering and bias. Identifying unjust and politically oppressive practice must be part of the path to justice. Understanding the political construction of knowledge organization is essential for the theory of information service in order to build a more just professional practice.

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

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

The acquisition of foreign research materials has been an important activity of US university libraries from the early 19th century to the present day. Assesses the extent of bibliographic control over foreign published books and reviews previous evaluations of national bibliographic utility hit rates and quality assessment studies of bibliographic records. These reviews suggest that the bibliographic control of general research books is better than the bibliographic control of foreign research books. However, the previous studies' varying sampling periods and techniques necessitate a baseline study to confirm the asserted difference of these 2 groups os books. Results of the baseline study reported here conforms a lack of bibliographic control for a substanbtial portion of foreign books, the presence of LCC, and the level of bibliographic description shows that the quality of bibliographic records for foreign books is lower than the quality of records for domestic books

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

Three methods of access to musical works on sound recordings are: name-title added entries; title added entries; and contents notes, which may allow access to works through keyword indexes. The purpose of this research was to learn about the comparative effectiveness of standard OPAC retrieval techniques utilized to retrieve sound recordings of musical works. A sample of recorded musical works was searched in CLIO (Columbia Libraries Information Online). The number of musical works per sound recording, and the work's type of title were tested as influencing factors in the success of various retrieval techniques. Retrieval-set sizes, and the number of steps required to locate a target record were also measured for each of the retrieval techniques. Keyword retrieval is shown to be effective. The comparable effectiveness of keyword searching with conventional title searching appears to be dependent on the number of works contained on the recording. Keyword retrieval is not as successful as title searching when title entries are provided.

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.
