Abstract Google is the search engine of choice for most Internet users. For a variety of reasons, librarians and other expert searchers do not always use Google to its full potential, even though it provides capabilities not possible in traditional bibliographic databases and other search engines. Applying expert searching principles and practices, such as the use of advanced search operators, information retrieval strategies, and search hedges to Google will allow health sciences librarians to find quality information on the Internet more efficiently and effectively. 相似文献

Educational supplementary bibliographic relationships from FRBR point of view: A Canadian Case Study
Alireza Noruzi Clément Arsenault 《Library Collections, Acquisitions, and Technical Services》2013,37(1-2):66-72
PurposeOne of the aims of library catalogs is to clearly represent the relationships existing between two or more bibliographic entities, enabling users to make sense of these relationships. Educational bibliographic relationships are the relationships between an educational work, such as a textbook, and its related works. The main interest of this study was to understand the nature of the supplementary work-to-work bibliographic relationships among educational works and the constitution of educational bibliographic families in the Canadian context using AMICUS (the Canadian national catalog). A thorough understanding of educational bibliographic relationships is required for understanding the Functional Requirements for Bibliographic Records (FRBR) supplementary relationships.Design/methodology/approachWe studied the extent and size of educational bibliographic relationships in the bibliographic universe found in the AMICUS catalog. This is an empirical investigation into the nature and extent of educational work-to-work bibliographic relationships by examining title of works, notes and added entries in bibliographic records. The study was carried out between September 1st 2010 and December 22nd 2010 and examines educational bibliographic relationships between Canadian 2009 publications in each class of the Dewey Decimal Classification (DDC). In other words, this study poses two main questions: What is the structure of educational supplementary bibliographic relationships in Canadian publications? Do significant differences exist across the ten DDC classes?FindingsResults show that 595 works of the 2009 bibliographic records in the AMICUS catalog contain an educational supplementary bibliographic relationship. Of the Canadian publications with an educational supplementary work-to-work bibliographic relationship that were studied, the rates of educational bibliographic relationships were relatively high in the fields of Science (27%), Technology (22%), Social Sciences (20%), and Language (19%). The results of this study suggest a set of guidelines for the establishment and maintenance of educational bibliographic relationships.Originality/valueThis is the first research to examine the educational bibliographic relationships, as supplementary relationships. 相似文献

ABSTRACT This paper analyzes cataloging rules for Korean materials focusing on the McCune-Reischauer (MR)1 system, the Korean romanization scheme currently used in the United States. This system has been used for a long time in many Western countries, and was officially adopted by the Library of Congress (LC) for use in the cataloging of Korean language materials. Considering users' information-seeking behavior and searching abilities, however, the MR system has many drawbacks for increasing users' ability to retrieve information. This paper analyzes bibliographic records in academic libraries, the LC, and the Research Libraries Information Network (RLIN) to identify the issues and problems of the MR system. A user survey conducted demonstrates that the MR system is not a user-customized tool based on users' searching ability. Several solutions are suggested to overcome the limitations of the MR system. 相似文献

ABSTRACT This bibliographic essay examines recent (1994–2006) research into the evaluation of reference effectiveness. Different methods for evaluating traditional in-person reference services are compared and contrasted from an unobtrusive or obtrusive methodology perspective, including those that use the “Willingness to Return” factor and the Wisconsin-Ohio Reference Evaluation Program (WOREP). A review of emerging trends is provided as well as recommendations for future research. 相似文献

ABSTRACT This article illustrates the collaboration of three entities- the library, its online system and the authority service vendor-to achieve online authority control in a medium-sized academic library efficiently and cost-effectively. The authority service vendor checks and revises (as needed) the headings of the library's new bibliographic records, providing new authority records for them. Through a separate notification service, the vendor also provides revised authority records for the existing authority file, alerting the library when in-house online maintenance is needed. In this online environment, authority records and bibliographic records are maintained automatically by the vendor authority service. Thus, using various authority heading reports which can be generated by the local online system in conjunction with the notification service, the library concentrates its authority work on the elimination or correction of obsolete headings. The authority vendor services are effective and reduce the cost of maintaining the online catalog. Ultimately, accurate standardized headings enhance the ease and effectiveness of online searching and retrieval for all who consult the library's catalog. 相似文献

ABSTRACT This article discusses how samples of records for laboratory IR experiments on OPACs can be constructed so that results obtained from different experiments can be compared. The literature on laboratory IR experiments seems to indicate that the retrieval effectiveness (recall and precision) is affected by the way the samples of records for such experiments are generated. Especially the amount of records and the subject area coverage of the records seems to affect the retrieval effectiveness. This article contains suggestions for the construction of samples for laboratory IR experiments on OPACs and demonstrates that the retrieval effectiveness is affected by different sample size and composition. 相似文献

ABSTRACTAlthough it is not yet known for certain what will replace MARC, eventually bibliographic data will need to be transformed to move into a linked data environment. This article discusses why the National Library of Medicine chose to add Uniform Resource Identifiers for Medical Subject Headings as our starting point and details the process by which they were added to the MeSH MARC authority records, the legacy bibliographic records, and the records for newly cataloged items. The article outlines the various enhancement methods available, decisions made, and the rationale for the selected method. 相似文献

Abstract By designing an innovative practicum for a graduate information science student, a library can provide Internet training tailored to fit the specific needs of its college faculty and staff. In addition to program credit, a student gains bibliographic instruction experience in a real world, evolving library environment, and both institution and student benefit from a project that addresses the genuine needs of the institution. 相似文献

AbstractNational bibliographies have been identified as a crucial resource for historical research on the publishing landscape, but using them requires addressing challenges of data quality, completeness, and interpretation. We call this approach bibliographic data science. In this article, we briefly assess the development of book formats and the vernacularization process in early modern Europe. The work undertaken paves the way for more extensive integration of library catalogs to map the history of the book. 相似文献

The Citation Cloud of a biomedical article: a free,public, web-based tool enabling citation analysis
Neil R. Smalheiser Jodi Schneider Vetle I. Torvik Dean P. Fragnito Eric E. Tirk 《Journal of the Medical Library Association》2022,110(1):103
Background:An article''s citations are useful for finding related articles that may not be readily found by keyword searches or textual similarity. Citation analysis is also important for analyzing scientific innovation and the structure of the biomedical literature. We wanted to facilitate citation analysis for the broad community by providing a user-friendly interface for accessing and analyzing citation data for biomedical articles.Case Presentation:We seeded the Citation Cloud dataset with over 465 million open access citations culled from six different sources: PubMed Central, Microsoft Academic Graph, ArnetMiner, Semantic Scholar, Open Citations, and the NIH iCite dataset. We implemented a free, public extension to PubMed that allows any user to visualize and analyze the entire citation cloud around any paper of interest A: the set of articles cited by A, those which cite A, those which are co-cited with A, and those which are bibliographically coupled to A.Conclusions:Citation Cloud greatly enables the study of citations by the scientific community, including relatively advanced analyses (co-citations and bibliographic coupling) that cannot be undertaken using other available tools. The tool can be accessed by running any PubMed query on the Anne O''Tate value-added search interface and clicking on the Citations button next to any retrieved article. 相似文献

AbstractThe researchers extracted a disproportionate stratified random sample from 40?years of thesis bibliographic records at Concordia University in Montreal, Quebec. Match rates for thesis authors in the LC/NACO Name Authority File and in Canadiana Authorities were examined. ProQuest digitization of older theses, the creation of an institutional repository, the move to electronic theses and dissertations in 2011, and the implementation of vendor-assisted authority control in 2017 impacted bibliographic records. In addition to the dearth of matches in general, results uncovered false matches and significant changes to Library and Archives Canada thesis authority control practices over the years. 相似文献
