Abstract

Looks at access problems that occur when the citations from indexes for articles in series differ from the way the items are catalogued. To illustrate the difficulties encountered,a search was conducted in the online catalogues of various libraries and a comparison made between the bibliographiuc entries found to citations both in electronic indexes and in authors' references. The series: New directions for community colleges (NDCC); was chosen as it has kept the same title, ISSN and editors since 1973; yet is still illusive to identify. Each issue of NDCC, beginning with issue 1, 1973, was examined for citation information, numbering systems and changes in description on the title page. The online catalogue at Ohio State University (OSCAR) was checked to see how each issue was handled over time. Indexes consulted included: ERIC, Education Index; ArticleFirst; and CARL UnCover. Results indicate that the ramifications of local cataloguing decisions affect all areas of librarianship. In this electronic age, the need is great to integrate the various sources of information needed for a patron to go from citation to piece in hand

Abstract

We describe the intellectual and physical properties of books as manifestations, expressions, and works and assess the current indexing and metadata structure of monographs in the Book Citation Index (BKCI). Our focus is on the interrelationship of these properties in light of the Functional Requirements for Bibliographic Records (FRBR). Data pertaining to monographs were collected from the Danish PURE repository system as well as the BKCI (2005-2015) via their International Standard Book Numbers (ISBNs). Each ISBN was then matched to the same ISBN and family-related ISBNs cataloged in two additional databases: OCLC-WorldCat and Goodreads. With the retrieval of all family-related ISBNs, we were able to determine the number of monograph expressions present in the BKCI and their collective relationship to one work. Our results show that the majority of missing expressions from the BKCI are emblematic (i.e., first editions of monographs) and that both the indexing and metadata structure of this commercial database could significantly improve with the introduction of distinct expression IDs (i.e., for every distinct edition) and unifying work-related IDs. This improved metadata structure would support the collection of more accurate publication and citation counts for monographs and has implications for developing new indicators based on bibliographic levels.

Abstract

Information professions identified the need for a set of standard metadata almost as soon as the WWW became a reality. Several initiatives have already identified the types of bibliographic information that would be necessary to describe and locate an electronic publication. The descriptors identified in the OCLC/NCSA Dublin Core are combined with those assembled by the Coalition of Networked Information and the Internet Engineering Task force to produce a list of electronic citation elements. Advocates embedding these citation elements within electrinic documents through the use of HTML<META>tags and other markup techniques. There is also a call to cataloguing librarians to contribute their expertise in information resources management to document being prepared for the WWW in order to influence the quality of electronic publication from the insides

Abstract

In current cataloging practice, the identification of an item as a member of a particular work set is accomplished by assigning a main entry heading, or main entry citation, in the bibliographic record representing that item. The main entry citation is normally comprised of a primary author name and the uniform title associated with the work. However, the quality of bibliographic records varies, and this means of identification is not universally used by catalogers. Thus, consistent identification and retrieval of records representing editions of works is not guaranteed. Research is reported that investigates the extent to which records that are members of a particular work set may be automatically identified as such.

Abstract

This study investigated name changes of women authors to determine how they were represented in indexes and cited references and identify problem areas. A secondary purpose of the study was to investigate whether or not indexing services were using authority control and how this influenced the search results. The works of eight library science authors who had published under multiple names were examined. The researchers compared author names as they appeared on title pages of publications versus in four online databases and in bibliographies by checking 380 publications and 1,159 citations. Author names were correctly provided 81.22% of the time in indexing services and 90.94% in citation lists. The lowest accuracy (54.55%) occurred when limiting to publications found in Library Literature. The highest accuracy (94.18%) occurred with works published before a surname changed. Author names in indexes and citations correctly matched names on journal articles more often than for any other type of publication. Indexes and citation style manuals treated author names in multiple ways, often altering names substantially from how they appear on the title page. Recommendations are made for changes in editorial styles by indexing services and by the authors themselves to help alleviate future confusion in author name searching.

Abstract

Audiovisual materials present special difficulties for cataloguers by virtue of the fact that they must display the materials and take the cataloguing information from the title screens which may be inconsistent with data on the labels. The chief source cataloguing concept for audiovisual materials was examined through a comparison of citations from fully catalogued audiovisual records and their corresponding citations from bibliographic sourcebooks. A complete printout was taken of all AVLINE (National Library of Medicine's Audiovisual Online Catalog) records for videocassettes, slides and software. The comparison revealed much similarity with title and other title information, however, series, producer, credits, and dates were more completely described in the fully catalogued records than in the sourcebook citation. There was no evidence to support cataloguing using only eye readable materials. Cataloguing using the chief source of information consistently provides more bibliographic data

Abstract

New users encounter numerous stumbling blocks in their search for periodicals, including use of indexes; understanding the citation; searching the online catalogue for the periodical record; interpreting the periodicals holdings; and finally locating the item on the shelf. Each step presents problems that users bring to the reference desk. Suggests user oriented solutions relating to cataloguing practices, screen design, and linking local holdings to periodical databases. Increased collaboration between librarians and those creating the records and providing the access is essential for meeting end user needs

Abstract

The rapid growth of the Internet has outstripped conventions for citing material from that source. Distinguishing material as a computer file does not provide sufficient information about the platform necessary for reading it. The URL provides useful information, but augmenting it with other details such as author and date not only provides a more meaningful citation, its similarity to conventional bibliographical notation lends a greater degree of legitimacy in academic discourse. Considers information derivable from the URL, and HTML documents (including non displayed source text), in order to derive bibliography and only text citations for various kinds of material and proposes the development of a consistent bibliographic referencing method that emerges from Internet based file formats and overcomes such problems as the lack of specific pagination, long the mainstay of the traditional cataloguer and library user. The conventions proposed are also applicable to Gopher, FTP, Usenet News, periodicals distributed by listservers, and electronic mail

Abstract

Discusses the role of the URL as a menas od uniquely identifying an item of information on the WWW in the context of traditional methods. Includes: standard bibliographic description; LoC card number; ISBN, ISSN; MEDLINE Unique Identifier and OCLC Control Number. Presents the general URL model and the basic structure of URL codes. Discusses specific URL structures: file related URLs (file and ftp); WWW URLs (http); Gopher URLs (gopher); electronic mail URLs (mailto); Usenet newsgroups URLs (news); and remote login URLs (telnet and tn3270). Notes other proposals for identifying Internet resources and services that often become misinterpreted as URLs and lists some of the characters which may not be used within a URL. Although the URL is an official standard for referencing WWW resources, it is not yet recognized as a universal citation model for Internet resources

Abstract

The vast majority of the current author name disambiguation solutions are designed to disambiguate a whole digital library (DL) at once considering the entire repository. However, these solutions besides being very expensive and having scalability problems, also may not benefit from eventual manual corrections, as they may be lost whenever the process of disambiguating the entire repository is required. In the real world, in which repositories are updated on a daily basis, incremental solutions that disambiguate only the newly introduced citation records, are likely to produce improved results in the long run. However, the problem of incremental author name disambiguation has been largely neglected in the literature. In this article we present a new author name disambiguation method, specially designed for the incremental scenario. In our experiments, our new method largely outperforms recent incremental proposals reported in the literature as well as the current state-of-the-art non-incremental method.

Abstract

In this article we present FLUX-CiM, a novel method for extracting components (e.g., author names, article titles, venues, page numbers) from bibliographic citations. Our method does not rely on patterns encoding specific delimiters used in a particular citation style. This feature yields a high degree of automation and flexibility, and allows FLUX-CiM to extract from citations in any given format. Differently from previous methods that are based on models learned from user-driven training, our method relies on a knowledge base automatically constructed from an existing set of sample metadata records from a given field (e.g., computer science, health sciences, social sciences, etc.). These records are usually available on the Web or other public data repositories. To demonstrate the effectiveness and applicability of our proposed method, we present a series of experiments in which we apply it to extract bibliographic data from citations in articles of different fields. Results of these experiments exhibit precision and recall levels above 94% for all fields, and perfect extraction for the large majority of citations tested. In addition, in a comparison against a state-of-the-art information-extraction method, ours produced superior results without the training phase required by that method. Finally, we present a strategy for using bibliographic data resulting from the extraction process with FLUX-CiM to automatically update and expand the knowledge base of a given domain. We show that this strategy can be used to achieve good extraction results even if only a very small initial sample of bibliographic records is available for building the knowledge base.

Abstract

Author name disambiguation (AND) is a challenging problem due to several issues such as missing key identifiers, same name corresponding to multiple authors, along with inconsistent representation. Several techniques have been proposed but maintaining consistent accuracy levels over all data sets is still a major challenge. We identify two major issues associated with the AND problem. First, the namesake problem in which two or more authors with the same name publishes in a similar domain. Second, the diverse topic problem in which one author publishes in diverse topical domains with a different set of coauthors. In this work, we initially propose a method named ATGEP for AND that addresses the namesake issue. We evaluate the performance of ATGEP using various ambiguous name references collected from the Arnetminer Citation (AC) and Web of Science (WoS) data set. We empirically show that the two aforementioned problems are crucial to address the AND problem that are difficult to handle using state-of-the-art techniques. To handle the diverse topic issue, we extend ATGEP to a new variant named ATGEP-web that considers external web information of the authors. Experiments show that with enough information available from external web sources ATGEP-web can significantly improve the results further compared with ATGEP.

Abstract

Describes the experience of data conversion and migration at the libraries of the Home Office (HO) and the Dept. of the Environment (DoE), UK. Both HO and DoE libraries had changed from Anglo-American code cataloguing to AACR2 cataloguing in the mid-1970s. Both libraries were selective in identifying records for conversion initially to BLAISE-LOCAS. Conversion to integrated library systems from BLAISE-LOCAS MARC tapes produced problems in both libraries with location/holdings fields which were largely resolved at HO, but not resolved at DoE. HO experienced problems converting to a system with fixed field lengths. HO converted subject keywords to form a rudimentary, non-standard thesaurus which required the addition of Broader Term and Narrower Term to meet the challenge of computerized searching. DoE converted a non-thesaurus subject index to an authority file, but continued to maintain the index on a stand-alone DataEase application for use by cataloguers. Neither library converted acquisitions data

Abstract

How are the boundaries of information objects to be defined in the networked electronic environment and what is the role of our retrieval systems in providing access where these boundaries are uncertain? The authors consider these questions in light of longstanding problems surrounding the definition of the "work" in the print environment. In particular, they examine the role of the index in providing access to the collected works of the individual writer. They review the discussion in the indexing literature of the "long index," and the close relationship between the functions of indexer and editor in collected works projects. And they treat the role of the index in constituting as a self-contained corpus the disparate types of text that make up a writer's lifetime output. Finally, by way of example, the authors turn to the extensive indexes to Sigmund Freud's psychoanalytic writings.
